The bottom of the Centauri Carbon 2 is plastic that's already cracking on people? Seems like a major design flaw to have a chamber that's constantly heating and cooling and undergoing vibration.

broke my pinky(and a few other things) a while ago and this has been helping.

Should I try to use sensorless homing on my first printer build, or is it something I should wait for more experience to try?

the biggest pill in 3d printing is that unless you got strict size or mass constraints or need something that will take very high heat, petg is the solution to every problem
if it's not, you just add more petg to your part until it starts being a solution
if it's still not, your part design is plain shit and you should be ashamed
ten bucks a kilo, unbeatable price, print it cold and slow on a decade old ender and laugh at bambubabs playing with the latest blend of pla++ and voronfags torturing themselves with nylon and smoking mind-numbing asa fumes

>>2997285
yes

>>2997295
I've had PETG fail more than ASA. And I can never get it to come out smooth. ASA prints perfectly for me, PETG is a mess and no amount of drying improves it.

>>2997295
PLA is about the same price as PETG, prints nicer, and is mechanically superior.

>>2997295
rent free huh my "omg cool plate" brand plate holds petg, pa6-gf, and tpu on my a1. I am temped to try abs. it just works let me ask how many fails you deal with on your ender?

>>2997295
You know for the longest time Creality / ender 3 fags used to argue with me about ass poisoning bejng a thing

They said I was making it up

And that “I just hated ender 3s because you can’t level a bed”

Kept posting pictures of the prusa kits i built saying nah man I used to have an ender too but I sold them for more than I paid for them (I bought them at microcenter during the pandemic $75 printers + free roll of inland PLA sold for $120 each kek plus however much profit I made off of them in a print farm)

>>2997317
pla is inferior in every single metric except being foolproof
baby's first filament, only good for articulated dragons
>but muh tests
all the tests are printing petg fast and with cooling on, that wrecks it
if you see a test where petg's layer adhesion is not nearly equal to its strength in xy plane, it's forged data by big pla, they deliberately printed it wrong to promote their cornstarch
220 degrees, slow, preferrably with a fat nozzle, you get parts that are as strong as abs but with none of the warping or fumes, superior wear and chemical resistance and perfect layer adhesion
true engineering plastics are superior, but between printer requirements and price difference, rarely worth it, just throw more petg at it if it breaks
>>2997322
it makes weird noises but otherwise works flawlessly for the last couple years, aside from that one time i killed a 12 hour print because kapton tape holding the cooling duct failed
>tempted to try abs
abs is largely obsolete, decent properties but shit to print, especially on an open printer
it has its uses, it's cheap and takes post-processing better than most plastics including its supposedly replacement asa, good for cosplay props that you gotta glue, sand and paint, kinda shit otherwise
>>2997327
doesn't have to be an ender, anything simple, slow, open, pre-klipper
ender clones, old prusas, kp3s, what have you, most people don't need more than that and a spool of petg

>>2997330
>all the tests are printing petg fast and with cooling on, that wrecks it
Ball's in your court. Either find test data that does represent your claims, or do the tests yourself.
>220 degrees
Kinda cold for PETG.

It's kinda sad how New York and soon California illegalized open-source printing

Just boughted a P1S to get into this 3d printing thing since electronics tinkering with toy cars, drones and stuff seems fun and was fun in uni.

Like half the budget went to my filtration/ventilation system pulling filtered air out my window so neither me or my neighbors get the assma years down the line. Also a hepa air purifier just for the room itself. It should be overkill as fuck for just printing pla/petg but I'm not taking any chances.

I live at the second floor with wooden floor and dont want do be an asshole, so what should I do for vibration? AI suggested a concrete layer, some foam and then the printer on top, what would you guys do?

>>2997343
Get a concrete paving slab. (Heavier is better. You can also print a little enclosure for the slab to go in, if you want it to look nicer. It's just a mass damper.)
Put an antivibration mat on it. (Don't get anything too thick)
Put the printer atop that.

You can also print and assemble "HULA" feet with some extra parts, and they work really well, actually.

It's only ever going to be as solid as whatever you're putting it on though. Workshops have like proper screwed-to-the-ground benches and stuff. But, just whatever has good contact with the ground will spread the vibration over a wider area. There's probably some logic to putting a larger antivibration mat under table or bench or whatever you've got the printer on. But, it's really kinda overkill at that point.

>>2997345
I got those tiny anti-vibration feet from the Bambulab shop since they were like a dollar, would I be skipping the mat then and just putting these + feet adapter or whatnot directly on top of the concrete slab? Or is the mat still needed?

>>2997349
Those feet are shit and are kinda misleading. They're basically a counter to vibration from outside so they're great if you're running two printers on the same unit so the vibration from one printer doesn't affect the other. It doesn't do the same when it's just a single printer.

Oh, shit my bad, I fucked a part up.

So, you want this basically.

I don't know if you have an AMS, but, fulled loaded it's like 4KG of filament right on top of your printer which moves the centre of mass pretty high up there, and you probably don't want to do that, despite the fact everyone does it for some reason, and they even market them like that.

I didnt think of that. I just made the chip areas real snug, the chips pretty much snap in. I think in the final box will have some dots of glue to help

I need to make a mould for silicone, would rubbing vaseline oil on the plastic be enough to prevent the silicone from getting stuck to it?

How would 98D GF TPU compare against Nylon in terms of abrasion resistance? Im using 95D TPU right now and it seems like nylon is maybe 10% more abrasion resistant. Ive been toying with a product right now in a pretty small market. Maybe 20-30k a year in global sales if im lucky. The nylon product that is currently sold is better, but if gf tpu is very similar performance wise then I can get a little more creative than whats currently offered. My ultimate goal is to maybe have a small extrusion line and make my own glass filled tpu as currently this stuff is like $35 usd per kg.

>>2997363
Yes. But vaseline is pretty thick stuff. By mixing vaseline, candle wax, and mineral oil in different ratios, you get get something of a better consistency. I made a mould release from vaseline and candle wax that can be rubbed into the layer lines like a pastel or crayon, without forming meringue-like soft peaks.

>>2997364
Where do you get such hard TPUs? I've only ever seen as hard as 72D, plus a bunch of things in the A scale.
Fibre-reinforced filaments may have issues with their fibres in the debris they leave behind.

>>2997365
it's not normal vaseline it's liquid paraffin (just found out that in english nobody calls it "liquid vaseline", my bad) so it has a similar consistency to mineral oil, would you say that it's good enough on its own? Otherwise I'll try your method, I have candle wax but I might have to buy some vaseline

>>2997366
Too thick and it forms solid clumps or elastic blobs, too thin and it will flow and pool at the bottom. Gotta use your own judgement, if it's like a thin ointment it should be good. Otherwise you may have to thicken or thin it as necessary. Pretty easy to test either way. I hear casting silicone doesn't really stick to much anyhow, rather your mould release is going to be doing more of a mechanical job (stopping the silicone getting lodged into the layer lines) than a chemical job.

>>2997367
thank you very much, that gives me some food for thought, I'll post the results here once it's done

>>2997365
meant to say 95a and 98a. Had shore hardness mixed up with fabric denier.

Is there also a D scale? The 95a and 98a are pretty easy to find. Not sure if I have seen fiber reinforced 95a yet but its probably out there.

>>2997378
>Is there also a D scale?
Yes. The may be another scale or two other than A and D, but they're seldom used for 3D printing. 90/95/98A is by far the most common TPU. If you really look around you might find 85A and 80A. I think a few places make a 65D or so (probably protopasta and/or ninjaflex) but it's a bitch to print. I bought some CC3D 72D from Amazon, which MyTechFun reviewed a year ago or so. He's also apparently reviewed a 58D carbon fibre TPU. Apparently Bambu TPU for AMS is 68D. Then there's a 15% glass fibre reinforced 67D that LostInTech just reviewed, I hope MyTechFun gets his eastern euro mitts on that for a good test. I'd also like to see him test a TPU CF-core filament, should be better at avoiding diminished layer adhesion coming from fibre reinforcement.
There's also some non-TPU TPE filaments, and PEBA filaments too. And foaming versions of TPU and PEBA for an effectively softer printed model.

What material properties do you need, and which do you not need? Would you be ok making the part thicker or thinner to have the right amount of flex after changing the shore hardness? If you take a look at MyTechFun's spreadsheet he rates a few useful specs of TPUs, including friction, but not including wear resistance at least in my old copy. I know he has done wear resistance tests in the past.

>>2997386
The main properties I need it for is very little flex and abrasion resistance.

I already have some prototypes in 95a tpu and it works pretty well compared to nylon. My thinking is that glass filled nylon would beat it out on abrasion resistance, but glass filled tpu would beat standard nylon. Then regular nylon would beat standard tpu. Im basically competing against injection molding in a very small niche and where I could probably win is through color options and just being a little more abrasion resistant than bone stock nylon would be a good selling point. I dont think anyone does glass filled for this product.

>>2997389
What sort of abrasion? If it's rubbing on something smooth, then something hard and low-friction like POM or PTFE-filled filament might be a better way to go. If it's oscillating on something rough, then a semi-soft thing like 85A TPU might grip and skip, seldom sliding. Rolling elements and lubricants are also options.

>>2997386
Also that lostintech video is what brought me here. According to that chart that siraya tech 67D would actually be harder than 98a?

Would be printing at 100% infill. Worried about layer adhesion as well. Wont hurt to buy the stuff and experiment with. Basically just need something that wont shear off and can stand up to a fair amount of friction.

>>2997390
Occasional contact with cement (like a trailer bumper)

The longer it lasts the better.

Just wondering, had anyone here tried PythonSCAD? I recently found it and really like it (at least, as someone who's comfortable with python).
It's a fork of OpenSCAD that lets you use ordinary python to construct models, instead of being limited to the clunky scripting OpenSCAD normally requires. Also adds a lot of shorthands and convenience features so scripts feel way more concise.
Won't replace a full CAD program of course, but it seems a lot more usable than OpenSCAD to me. Having an actual real programming language behind it is so much less limiting.

>>2997393
just remember it's got to not shatter too because I've seen similar produced "bumpers" that shattered on abrupt contact in an application (not vehicle) that happened as a normal part of the intended use.

Shame that PET filament is so hard to find (both physically and google-y since it just sends you to PETG hell if you try), and when you do find it it's marked up as muh engineering filament instead of being sold for what it is- literal bottle plastic, straight out of the same granules

>>2997421
Economies of scale. At this point I think PET-CF is cheaper than PET.

>>2997421
If you want to print PET so bad just stick a molecular sieve before the nozzle and use regular PETG. You need to have one of those longer hotends or you simply won't have any thread left to screw the nozzle itself. I don't remember on the top of my head the particle size of glycol, maybe other anons can chime in. Your print speed will tank horrendously unless you upgrade the extruder motor-gear assembly too.

How much ventilation do you typically need with ASA? My printer would be in another room, but I would like to also be in there as an office and not keep it in a tent. I thought about grabbing one of the filtration systems pot growers use and mounting it to the ceiling and covering ac/heat vents in that room.

>>2997455
>How much ventilation do you typically need with ASA?
All of it, unless you only come into the room only to grab the prints. You don't want to find out 10 years later that ASA FDM turned out to be more carcinogenic than previously thought and you'll panic about cancer every time you feel a slight discomfort. If you plan to sit there, just make a proper tent with an air duct dumping the toxic shit out of the window.
No seriously, you are melting plastic and not the funny cornstarch kind like PLA either.

That's what I figured, I can put it in the garage for the time being. Maybe some amateur ductwork and a filter can get me where I want to be(inside so I can grab my prints in my boxers).

Has anyone tried using one of those Bento Boxes? Do they do anything? Are they worth it?

>>2997410
Damn did not even think that was possible. I could see PETG just shattering, but didn't even consider TPU could just shatter. Wouldn't just regular nylon be prone to shattering as well? Have never seen the nylon components shatter.

>>2997469

>>2997474
Into some ducting out a window? That's what I thought, the only reason I want the bigger unit is that I'm thinking about picking up another printer and having them both going. Ducting from both of those into a carbon filter and out the window sounds good enough to me.

>>2997443
Isn’t the glycol actually part of the polymer?

>>2997469
Fibre reinforced TPU still has high impact resistance, but its elongation at breaking point is substantially shorter, so it depends on the kinds of impacts it needs to resist. 95A is basically immune to any impact if you can scale the print right, I assume stiffer TPUs are worse for this. That 72D TPU has somewhat worse layer adhesion, which will harm it.

my print needs to not be stringy as shit.

Is there a kind of library of printable components? Say, I need to attach two halves of my print in a separable way but I don't wanna design a whole mounting system if I can take something that already exists. I could use something like a standard Gopro mount integrated into the parts, the CAD files for those are easy to find, but it sucks for printing, one half can only be printed in one orientation if you don't want it to break and the other can't be feasibly printed at all for anything but cosmetic applications.

>>2997508

That's not what I meant. I'm designing a custom bike light with a pair of those rain effect LEDs I found, for a bike with a weird seat tube shape that won't take standard mounts, and I need one half to stay on the bike and another to detach for charging. I said gopro as the first example of a standard mounting system I could think of, even if it was optimized for printing it's too big for my application either way.

>>2997519
I see, personally I've never heard of such a website sadly.
What about an arca mount? Could you just take the stl for something like this

Filters in 3d printing world seem like a meme. Think about how big and hefy air purifiers are. If printing really does spew all kinds of nasty shit then what's a little box with a few grams of carbon pellets going to do. Activated carbon is disputable effectiveness in terms of home use solutions. It's not until industrial scale air cleaners does it become effective.
It's like people are so hyperfocused on 3d printing their heads are stuck inside a little printer box. I am baffled at how people think a little square of hepa filter and handful of carbon pellets over the fan on a printer is going to do anything.
Maybe they're so used to printing little trinkets and convincing themselves of usefulness.
It seems like the air filters in printers are there so manufacturers can check off the air filter feature, but like come on. Stop and think about it for a second.

>>2997538
Need negative pressure and duct out the window at least. A too smol fan won't do anything despite a filter since air goes through printer cracks then anyway

My setup is p1s to hepa+charcoal filter to duct to blasting chinese exhaust fan to window seal out the window to the neighbors. And on the inside I have a hepa+charcoal purifier with sensor to make sure I don't fuck shit up. I really don't wanna get asthma or whatever down the line

>>2997512
Maybe GrabCAD?

>>2997538
The shitty little filters on the back of printers definitely have a limited effect. Instead I’d want at least a 20cm long cylinder full of activated carbon if I were pumping toxic bullshit into my living space. Or maybe some sort of ozone generator (with a catalyst to break it down afterwards), or titanium oxide free radical UV generator. Though who knows if the breakdown products of styrene are more benign than styrene itself.

Window vent makes by far the most sense, at which point also having activated carbon seems positively useless. What, you’re filtering the air before it exits your house, the fuck?

What printers do you all have? Tell me about them.

I have a Duender I put together myself. Quite custom, it has a heated insulated chamber that reaches 80C and all electronics moved to the outside. Two Creality 4.2.2 MCU's managed by a Pi 2 Zero running Klipper.

>>2997671
I have an old Artillery Sidewinder that I want to build into a fat 300x300 Duender. Looking for a second one for now, used to always have a few of them in the marketplace feed but haven't found any locally lately.

>>2997670
Nah, but close. It's for a synth mod I'm doing.

>>2997671
Sounds like a good build. I reckon it was a learning experience. I have a Neptune 3 pro running off klipper on a pi. I changed the heating cartridge, hot end, and put in a .8 nozzle. Klipper made adjusting super easy. My prints aren't as fine resolution, but the thicker layer lines have grown on me. I have had to adjust my CAD to accommodate the larger print nozzle, but things print so much faster it doesn't matter when I have to make a few extra prints for proper fitment.

>>2997692
Larger nozzles are amazing. I don't understand why 0.6 isn't the standard.

>>2997693
Agreed. I made all of those changes at once. But I feel the nozzle was the greatest impact. Sure, klipper allowed for easier adjustment, but Marlin would accommodate the changes needed for a larger nozzle. To adventurous anons, don't be afraid to change the nozzle, there will be learning along the way, but it'll help you become more familiar with your machine. Errors are documented and other people have overcome them. Fear is the little death.

>>2997671
I have an X2D and a P2S.
The X2D has been nothing but trouble.

>>2997696
Sorry it's been troublesome for you anon. What are it's symptoms?

>>2997697
Whenever doing prints that use multiple filament it just cannot adhere to the bed right, keeps blobbing and stringing and just being compete shit.

If I print using just the main or Aux nozzles it's fine.
But the moment I get a print to use both it's a disaster.

i currently have an ender 3 v2 that i'm tired of fucking around with. i want something with a comparable print area that is considerably more reliable, and i want to be able to print ABS and CF. i also want to avoid bambu lab. is the elegoo centurai carbon the best option for for <$500?

>>2997701

Prusa, or I guess anything that's still "offline", I guess?
Another layer to it, is like you still have to slice the files themselves, and how much do you trust that your slicer isn't also spying on you?

>>2997699
Is it bed adhesion or layer adhesion that causes the failure? I'm not familiar with dual extruder printers. Are there settings in klipper that are specific to dual extruder prints?

>>2997708
>>2997699
Just reread the post to see it was bed adhesion. Has there ever been layer adhesion issues? Tried a glue stick or hair spray?

Where do anons buy their filament from in the EU?

>>2997701
I've had good luck with my elegoo printers, but I mainly print PETG. There are people that have made bamboo work offline. But as >>2997707 said how much can you trust your slicer. I understand the right to privacy. You'll have to carve your privacy away from overreaching entities these days.

Modded Ender 3 V2. Direct drive BMG clone with hardened gears, dual Z, bed from a K1, TZ 3.0 nozzle ecosystem, Hero Me 5015 duct, CR-touch, silicone nozzle brush, tie rods, but not linear rails. It’s reliably doing what I need it to do.
When I upgrade, it will be to an enclosed printer, ideally with a heated chamber and a toolchanger.

It’s not an objectively bad printer, it’s what I’ve got and after extensive modding it’s pretty capable, but it’s an old model thats just likely not worth your time. When you buy used, you’re inheriting all of the faults the previous user left it with, and with those old machines there’s a lot of room for user errors to accumulate in a bad printer. I’d only buy a used printer if I knew enough about how it functions to fix even obscure things going wrong, or if the design was so robust that I could trust it to still be in good condition regardless of what the first owner did.

Not too easy to answer because the naked results do not translate to the real world application.Here were my results. For the test setup I set
>bed to -200mm
>start heating bed to 100°C
>take measurements every 5 minutes
The extruder was turned off, so it was just another thermistor. And as you can see, with rising heat the difference between chamber and extruder temperature drifts apart further and further. I figured out that the chamber thermistor was at a very poor spot in a corner at the back wall. So the readings were unreliable. Fixed it with a 3cm bracket for the thermistor. Now there is roughly a 5°C difference between the extruder and chamber temperature.
While printing ASA (100°C bed, 270°C extruder) the printer has no problem with staying at the 55°C +/- 1°C mark. So I should have roughly 60°C above the bed, where the actual print is. As soon as the back ventilation turns off agian, the chamber heats up again. A nice tight and stable hysteresis. Did not push it any further than that yet.
So far it works and the insulation was cheaper than an active chamber heater. And the mainboard seems to stay a little bit cooler too. Probably because of the floor insulation.

x1cniggas, what do you use to heat your chamber? I'm giving ASA a shot currently and preheating the chamber with the heatbed is taking too long. Preferred chamber heater?

>>2997992
I mean does it have a noticeable effect on prints? Also, why not a partial insulation layer on the door?

>>2998002
Hard to tell. the worst warping with ASA I had with some very long and slender prints in the beginning. Never printed anything this long since then. Since then my ASA prints were more on the chunky side. Occasionally I had some corners that were lifting a mm or so. Nothing to spectacular and I could probably fight it with some more plate-soap-scrubbing or larger mouse ears. Maybe I should try to crank up the heat, clean the bed thoroughly and do some warp prone test prints. Maybe even at different temperatures. Right now I am too lazy though.

I already thought about putting some insulation on the door and just leave a little peephole. The glass door feels very warm, so the printer is losing some heat there. I just don't feel the need for more insulation right now. After heating up the bed I usually wait like 20-30 minutes anyway, so the bed stops warping from the heat change before I level the bed. Once I start to print the chamber has no problem holding the heat. Maybe I should test how far I can push the chamber temperature. I've just read that the web cam stops working at around 55°C and more. Also I might run into some issues with the stepper motors. Adding heat sinks might help though.
But maybe other anons had the same unreliable readings with their chamber temperature that I did and their true chamber temperature was much higher while running into those issues. So I might be able to push it further, now that my readings are more accurate.

Right now I've got some other more urgent personal issues to fix, before spending more time with this hobby.

>>2998009
I’d try insulating the door by double glazing. Adding a layer of acrylic with an air gap, and sealing around that air-gap so it doesn’t transfer heat through convection. Clear polycarbonate twinwall might be transparent enough to act as double glazing all on its own, that’s what I’ll be using to insulate my filament drier.

>>2997994

Do you preheat the chamber at all? Printing in a hotter chamber leads to less warping and better layer adhesion. Idk, I did get this bad boy though. Automatically kicking on when the bed is set to a specific temperature is pretty neat.

I've taken to printing pla in a 40C chamber. Highest interlayer strength i've felt third only to pet-cf and some nylons/pa's.
However, putting the filament in a dryer at typical pla temps and printing from that was enough to cause it to fail due to softening in the extruder.
If it's not printed from the hot dryer, then the filament moves fast enough that it prints perfectly.

>>2998207
Maybe you need an extruder cooling system like in the Qidi X Max 4.

I’ve always thought it possible to print regular PLA annealed as it comes out, by using an 80C chamber, but you’d need an actively cooled extruder to prevent heat-creep.

Though I do wonder if you need to use a drier with PLA at all. At the very least printing from the drier while it’s working seems superfluous, not like you’re printing silk.

>>2998229
Pretty good. The Neptune 4s have Klipper which is a nice upgrade for advanced features and more easily tweaking the firmware, but apparently they have limited RAM and can only handle a gcode file below 300MB before crashing.

I was thinking, all this filled plastics shed the glass/carbon strands thing, there's a finite amount of them on the surface, maybe post-processing can get rid of them entirely? Maybe ultrasonic bath? Tumbling with failed non-filled prints? If you can clean the surface, no new strands will be exposed unless you break the part.

>>2998297
Wet sanding/tumbling + lacquer should be fine. Even lacquer alone is probably enough. But abrasion alone likely won't work as the fibres are harder than the surrounding plastic, and so will abrade slower than the plastic. If anything I'd print fibre-core filament with a big nozzle, that should minimise the fibres breaching the surface.

Ever pre-printed your supports? Pic related is a test I just did.

I would just use the sharpie trick in this scenario. Takes two pauses instead of one, unless you use tree supports.
https://hackaday.com/2020/05/27/improving-3d-printed-supports-with-a-marker/
I use it surprisingly often.

Do you guys have a piece of shit printer that you keep around for sentimental reasons? My first printer was a Prusa Mini and I've since upgraded it with a bondtech extruder and revo hotend. I actually try to use it over my Core One and XL if the part is small enough.

>>2998364
No because we bought ender 3s and anet a8s that we can’t wait to immolate.

>>2998344
That's a good trick, I have never heard of it before. I may try it someday. Consider the following:
1. The pre-print method leaves you with a reusable support, which might be useful if you are printing very many of the same thing and want to use less filament.
2. Printing supports on top of extra-sparse sparse infill doesn't seem like it will work very well. This is the scenario I found myself in which led me to try out my little test.

The real gigabrain move is to print the support out of a dissimilar material (e.g. PETG for a PLA print), and design it to lock in place more positively. Maybe with a weak-point to break for it to come out. Using this to interlock permanent materials (e.g. TPU and ABS) is also extremely powerful.

It's not any moving parts crashing, it's like the printer suddenly isn't getting enough power...but only during the calibration? I can home axes and heat up the hot end with no issue.

I really should have just bought a new printer

What's the best tiny 3d printer? I'm guessing a Voron 0.2?

What material has probably the highest shear force? I have a part that is basically printed like a pencil standing up and I dont want it to snap in half. So whatever has the highest lateral load I guess is what it would be called? The print orientation cant really be changed either. I guess I could change the print orientation but it would be pretty weird to print it that way.

>>2998399
The Sovol Zero is pretty decent looking for a prebuilt machine, stock Klipper and a series of minor improvements over the SV08 that somehow vanished when they went on to the SV08 Max. A1 Mini is great for its price, Prusa Mini would be good for upgradeability if it had been updated in the last decade. Maybe they’ll make a Core 1 Mini upgrade kit. Not many manufacturers make small format printers, especially with the fancier modern machines it’s really diminishing returns below 250mm bed size. Make the build size half to 125mm, and you drop the price by maybe 10%. The potential advantage is in having a smaller footprint, and less power wasted in keeping the chamber hot, and if you have more expensive insulated walls and lower wattage chamber heater you might see more of an appreciable price impact in the smaller size. If I were making a PEEK printer I’d consider going small for that reason, and also if I needed to print a large PEEK part I’d be chewing through my wallet.

Maybe you should look at some delta machines? They can go fast, and often have a small but tall bench footprint, though it doesn’t seem like there are any multi-colour or multi-material deltas. I wonder how a delta toolchanger rack would even work.

>>2998403
I've got an old version of the MyTechFun spreadsheet. He measures vertical shear force but only for newer filaments. The top is:
>Creality PPA-CF - 158.6
>3DXTech PEI 1010 - 152.7
>Qidi PET-GF - 152.1
>Siraya PPA-CF Core - 142.8
Vertical shear force is a combination of regular shear strength and layer adhesion. The following is the layer adhesion list, which he has done for basically all filaments:
>AzureFilm PLA - 81.7
>PolyMaker PolyLite PC - 81.6
>Qidi PET-GF (as above) - 78.35
>Qidi UltraPA-CF25 - 76.05 (also has high vertical shear force)
Looks like a PPA-CF or a PET-CF are your best bet. I suspect CF-core filaments will be better given the same material, but I can't say for sure.

You really would be better off printing it horizontally for strength, the shear strength in the horizontal direction is routinely double that when printed in the vertical direction. Here PPA-CF wins out, though I'd still consider using PET-CF for its lower price. Either way you'll want to look into annealing.

Explain what it is you want to do so we can laugh at you.

ty men.

Believe it or not this is a key. The original is probably made of a stamped steel. I have used this plastic version fine, but I need to make it consumer proof. There will be end users that would break it whether its maraging steel or plastic but the goal is to just get less part failures. Probably going to have the key part flip out like a knife or push out like a thumb drive.

The current version requires you to try and break it, but I have sold things to thousands of people and nothing surprises me anymore. Just need these things to be quick to produce and cheap. I could print this horizontally but I would honestly probably get more bitching about the surface finish than the part breaking. Sick world.

There's an option to glue some piano/stainless wire down holes going the full length, so even if the plastic cracks you'll be able to pull it out again. Or to remelt in sand/plaster/etc. in bulk. Any extra processing time is something you'd want to use jigs and fixtures to streamline as much as possible, but it's that kind of value-added process, going above the bounds of 3D printing alone, that makes your product stand out among existing competitors. And dissuade low-effort undercutting slop-farmers.

Could you ditch some of those features to make it flat on one side? If I had an X2D or toolchanger I'd print it sideways on a support material and keep the shape as is, without that I'd attempt to trim one curved part so it can sit on the bed, pic related. Otherwise, there are non-serial print methods like >>2998341 and >>2998379. With the right designs of fixtures, you could print a reusable support piece that holds the trimmed piece like I described flat-side up, so the printer can print the curved bit atop it to complete the piece. Would take a fair bit of investment in the jig prototyping, but once it's done you're good.

Say, your gcode file could try to print this, and after the first bit has been printed you pause and take it off the bed and move it into the slot, then resume printing. Maybe you'd add a locating feature, like this thin hole to insert a wire or drill-bit or whatever.

>>2998415
Now that you mention it, I should be able to print it in that orientation on the left. It should be able to print flat like that if overhangs are not an issue. I think the slope is maybe 30 degrees and im not sure if I have ever printed an overhang less 45.

Just use ASA. If you've got the budget, polymaker makes a carbon fiber asa that is very resistant to warping, though it might still need bed conditioning and a draft shield/box if being printed on an open air printer.

>>2998561
That's wild. Maybe the guides got bent, so its the print head actually getting lower in the middle rather than the plate doing its best impression of a bowl.

>>2998625
It's far stupider than that. No, it's a rather thin aluminium plate only suspended upon the edges, with a heavy as fuck oven heating element underneath it, a magnetic topper + PEI plate on top. I compared it to the glass plate which was on it earlier and the difference is remarkable (glass plate is only tilted, stiff enough for it to not be a huge fucking problem). So the heating element already causes a bowl, once it warms up, since the aluminium plate is mounted wrong (technically one would need diagonal slot holes or something so it can expand without warping, but it's just normal drilled holes, not big enough ones), the bowl is exacerbated.

This causes localized problems too, e.g. it's near impossible to calibrate and even if calibrated, there's a very high chance of back pressure forcing hot filament back up into the hot end, which then clogs.

And all of this shit causes the strong desire for a VORON Trident or something like that in me, for I've put so much fucking effort into getting this shit piece to run, but my input was always ignored - until I collect data and prove that I was right all along.

I have a funny/stupid idea regarding webcams and klipper. There's a streaming format that specifically uses the pi's video encoding hardware (pic related) and that got me thinking: I'm using an old laptop instead of a pi, and it has a dedicated nvidia GPU in it. (GeForce GT 330M) I wonder if I could use that to accelerate video encoding of the webcam?

I don't know but I'd assume it would be fine, I haven't actually set it up yet. (Yes I know how stupid this sounds bear with me)

>for what purpose?
94% shits and giggles. Using an actual dedicated nvidia gpu on a debian command line only install for anything -even for something the cpu could handle just fine- just feels funny and satisfying. If I can pass off something to a hardware accelerator, why not?
6% because in theory, if I somehow managed to print at insane speeds, or rig 2 printers to be served at once from it, I could free up cpu cycles for more kinematics.

speaking of which, is there anything else I could concievably have klipper doing that might use a GPU or other laptop hardware? It'd be funny to say I've got a graphics card contributing to my printer.

How would I be able to print this without a fuckload of supports all over the place? I have a landscape that's hollow (because I'll be putting LEDs inside it), and there's a shitload of slits cut into it to let light pass through. When I run it through the slicer it shits the bed and puts supports literally everywhere, which makes sense, but at the same time seems like overkill.
Ideally I'd just cover the slits with a breakaway portion and just poke them out, but I'm not really sure what the process of going about that is. Like do I just put floating geometry there that has the gap that I need, or do I mark edges or something in Blender? How large of a gap is needed to enable it to print without supports but still be able to be poked out?
The slits are about 0.35mm wide, and 1mm deep.

I'm brand new to 3d printing, but I've been 3d modelling for over a decade, so I can rework the model if needed.

>>2998733
There is no need to. It is indeed this warped. There is no way to print on this.

>>2998734
You have too much bridging. One way would be to print supports in water-soluble material, then print the actual thing on top of it, although this either requires a two material printer or exchanging filaments mid-print.

>>2998734
print it on its edge instead

>>2998740
>There is no way to print on this.
What printer was it? Maybe try easing up on the bed springs.

Hey, I know it's nice to print something and be done, but another alternative it to print it normally with supports then use it like a mold for a different material on top, like papier-mâché or plaster.

In theory it could work. Definitely less support. Idk much about tuning the supports, but I probably could make them better.

>>2998741
I told myself "I don't need a 2 filament printer, I don't see myself ever needing to change colors", and just bought the base Centauri Carbon. Only found out later that it'd be useful for multi material prints. If I just print the support material, would I be able to print the actual model on top after?

>>2998745
I'd still run into the problem on a shitload of supports I feel like, even if it were solid-ish. I'm trying to prototype this as something I could potentially sell in the future as well (various dioramas of some of my art). So papier-mâché or plaster might not be the way to go.

>>2998760
That could work too, then just print out a rigid base and glue that on. Alignment could be an issue though.

Thanks guys, these have been some helpful suggestions.

>>2998763
You could do that without any supports with good enough part cooling. The mountain overhangs aren’t too steep, and the top edge could be bridged. That “perfect bridging” gcode modifier script would make it better though.

How thick is the landscape layer? If it’s less than 1.5mm you may have trouble, but if it’s 2-3mm I think you’d be fine.

>>2998771
The landscape layer is 1mm to let light through the slits, but I think I can thicken it to 3mm and it'd still be fine. 1mm was kind of an arbitrary number.
It's really hard to judge thickness in Blender. Seems thick as fuck in there, but when I pull out the calipers and give it a look irl it's thin as fuck.
Do you have a link to the Gcode script? Searching it up doesn't come up with anything useful. I'm using PLA, which as far as I'm aware is pretty normal as far as filament goes. I'm gonna give some test prints a go with the model pretty soon to see what I can get away with.

My mistake, it was a pull request into Orca directly. Was in the nightly 6 months ago, should be in the full release as of Orca 2.4.0.

Might need a bit of testing, and it still depends on your cooling fan setup. I recommend one 5015 fan at minimum, two is better.

Thanks a ton. I'll give that a go.
As for cooling, right now I just have the base for the Centauri Carbon, but I have exhaust vented directly outside with an inline fan on the vent to suck air out. Idk how cool I need things to be, but I'll play around with things. I want to avoid opening up the enclosure if I can help it as I have it in my room with no where else to put it.

I know it's gonna be a lot of testing and trial and error, hopefully by the end of it I'll have something that looks alright. End result is something like pic related. I mocked it up years ago, and it's been hanging around rent-free in my head ever since. Maybe if I figure this shit out I can give some of my other works a go too.

>>2998734
>>2998779
Oh those are slots? 1mm seems too weak and very likely to sag and jiggle, so yeah 3mm is a good idea, maybe more. You could make them thicker in the middle and thinner towards the slots, for strength without impacting light exit angle. Though if you're using a light filament colour that variable thickness could look strange, if you want it to be light I'd consider printing in black and painting it, so the light can't penetrate through the plastic. I'd also consider permanent support pillars/fins and connective links between the strips to span the slots, you could put such links significantly below the slot so light could diffuse around them. The permanent support fins wouldn't be a problem if you had an LED strip/filament or EL wire under each slot. Having the slots only go so deep and just embedding a thin EL wire or LED filament might be worth doing anyhow.

Yeah I see what you mean. That definitely seems doable. I do want the base to be removable so I can work on it and put the LEDs inside. Though I probably could just model slots into the base that the supports/pillars/fins slot into.
How I have the LEDs arranged shouldn't be a problem, since I can space things out on the inside. I've tested out different arrangements, and having them laid out front to back lights up all the lines, while side to side doesn't. The more densely I can pack LEDs the better though. I considered El wire, but I think it's a bit too thick and I want to keep the lines thin but defined, so they look less like holes in the model and more like a feature of the landscape.
I've just thrown together these supports on the inside and they don't seem to impact the light pattern at all, so I think if I do some that are spaced more consciously it should be alright.

The bed doesn't have springs. It's a completely custom built by an "engineer" who decided to ignore all of my advice when building it. Wasn't as much an issue with a glass plate, since that is rigid (and the heating element is powerful enough to ensure that localized cold spots don't happen), but when transitioning to PIE plates, the issue stared appearing.

But obviously, it worked! For like 3-4 prints until the warp became was too much.

>>2998835
What is the heated bed itself? A PCB heater? Aluminium slab is the way to go for warp-resistance, maybe you can tame any warping by bolting a sufficiently rigid frame to the underside of the bed instead. Worst case you just add shims, layers of aluminium tape on the sheet magnet should work fine.

>>2998876
An oven heating element. Probably if I make an X-Structure or something, like originally intended to. The problem is it's an old bed slinger, and the bed is already quite heavy for the single motor that drives it. So I am limited by the Y axis, in terms of speed, and I don't know if the additional weight would cause it to become even slower.
Which isn't great, even simple parts take a while already. Used to be faster but the sheer amount of not-well-thought-out modifications over the years led to this.

>>2998883
>bed slinger
Oh man. I guess I'd go for shims then, do a bed mesh when cold and then when hot to see if it's a thermal expansion issue, if so then you'll have to remesh it for every different bed temperature, and try to shim it to some compromise temperature that makes the coldest and hottest bed temps not too bowed. Do you ever print TPU, with its recommended 35C bed? Or nylon or polycarbonate?

Also post a photo or diagram of that oven heating element, because I can't picture how that would work at all.

is it supposed to be stupid annoying to dial in solid infill flow rate/spacing? i cant seem to find any premade calibration 3mfs for this specifically, and the other calibration prints seem to not hone in on my problem, which is just the tiniest overextrusion, which adds up after 10-20+ layers and results in a garbage top surface that makes the next one worse. im using an sv08 and orca slicer for reference. also heres part of a fursuit cause ppics get replies.

>bed mesh when cool and hot
Already did that, although a 11x11 mesh cool and 15x15 (the diagram your saw, I got lazy and made Claude make me a python script to visualize it from the console output since I don't like the diagrams in Klipper, and the select text thing in Klipper FUCKING SUCKS). The problem exists already in the cool state, but is exacerbated by the heat warping. Never printed TPU. Only ever PLA, ABS and PETG. I'm a big fan of ABS, what can I say? My prints from years ago on that hold up well.

I think what happened was that over time the heating element dragged the aluminum plate down by gravitational pull, which is why it wasn't a problem before. Then, after a while of sitting, the bed deformed, and the heating/cooling did the rest.

Not gonna give you a picture, but maybe tomorrow I make you a diagram anon. What I really need with this machine is pic related and a bottle of holy machine spirit oil.

I err on the side of slight underextrusion. Ratio of 0.955 I think. You're never going to fill in all the gaps between the walls anyway, especially without brick-layers. But I haven't exactly done strength tests to see whether I'm weakening my prints by 5% or by 25%.

Orca does have an extrusion ratio test, pic related, though it is only a few mm tall so you're not going to get too precise of a result. Maybe you can stretch it taller.

ive used those cards before and they were fine, but they are only ~3-4mm thick so the issue doesnt show itself in them. at some point i lost my orca settings and im reconfiguring it now. ill have to try making them taller and going off that.

these skadis hooks are 8mm thick in the stl, but im getting up to .5mm over overextrusion on them. im already dropping the solid infil flow rate to 95% and line width to .5mm, but the issue seems somewhat inconsistent. my pla filament is at ~13% humidity according to the sunlu drier box i have. ill try dropping the infill flow rate a bit more and see where it goes.

>>2998913
If you're getting inconsistencies, it may be that your extruder is struggling a bit with that filament at your maximum flow rate, so I'd print your test specimens at a low speed to get the worst case scenario.
Also that stringing is NOT what you should be getting from PLA, what did you dry it at 35C? Or is it some strange blend, or with carbon fibres?

>>2998914
i suspect the stringing is from setting the seam to random and scarfing the outer walls, in combination with suboptimal pressure advance settings. im not opposed to doing some postprocessing so the stringing doesnt bother me, but it would be nice to avoid.

its sunlu pla black and im drying at 40c. ive had issues with the extruder gear stripping the filament and it winding up stuck in the head, so it may be related to the extruder not performing as it should. i have the max volumetric speed set at 17mm^2/s for this filament becuse it seems like it can take it, but ill also run a test with it lower; id like to try and keep it high because it massively affects the speed of the prints. id rather mess with settings for a bit before buying a new hotend assembly, but if thats what it takes id rather that than print dogshit all the time.

>>2998917
>40c
I'd dry it closer to 45, though that really depends on how much you trust the heat distribution of your drier. Ideally your drier would measure internal humidity and tell you how much moisture your roll is releasing, but we do not live in such a world yet.

>>2998906
I just came to the conclusion that maybe, by clamping the PIE plate onto a glass plate, I could get entirely around this issue. It's retarded, but it just might work.

>>2998920
I'm surprised we don't see spring steel build plates on top of glass more often, but I guess the thermal conductivity of glass is reason enough not to. Now glass *underneath* a PCB heater might be pretty good, though differential thermal expansion might result in even more warping if you don't let them slide over one another.

>>2998929
Hmmm...both interesting propositions. But the thing is, since I don't use a PCB heater, I can actually use the heating element to it's fullest potential. Glass is wonderful and lovely, especially with Kapton, but only if the Z-Probe works...

>>2998919
ill give these all a try. thanks, fingers crossed i can get this thing dialed in well. kinda sick of fucking with the printer instead of the prints.

>>2998939
Could also just be that your filament is old and shitty. If it's stringing, it's expanding in the nozzle, and so you're bound to get inconsistent extrusion too. I couldn't say whether that could be fixed by drying. Sunlu recommend a 50C drying temp, if that doesn't work maybe the filament has irreversably hydrolysed.

you need multi-material. you print the supports in a different material and they separate like butter. gets a nice clean under and easy to remove.

also why not translucent filament? you can go a lot thinner without the slots and I understand you're fixed on that first idea but with a modern machine you shouldn't be. See the 10k variants on moon lamp to see what I'm talking about.

>>2998760
this is fire actually, instead of glue just make them a little wider than the frame with feet so they clip in. I fucking hate glue, glue is for broken prints not putting prints together in the first place.

>>2998941
>you need multi-material
Dumb question, but can I print the supports first and then print the landscape on top? Idk how I'd do a multi-material print without buying a completely different printer, or getting the multi-filament "upgrade" for the CC (which gets rid of the lid and vents fumes into the room which is a no-go).
>also why not translucent filament?
Mostly because of the multi material "problem". The slots seemed like a good compromise that worked with a single material. Swapping materials in multiple passes wasn't something that occurred to me or seemed possible (if it is).
Again, I'm brand new to this. The most I've printed so far was the boat, and then an adapter I made to vent the fumes outside.

>instead of glue just make them a little wider than the frame with feet so they clip in.
That kinda makes sense. Print out the strips on the side, give the base a little lip, then use the compression of the plastic to keep it in place like a spring. Printing on the sides would lean into the look anyway since the layer lines would go horizontally across the model.
Honestly when the dude first mentioned it, it didn't really make a lot of sense to me. But it's actually a really good idea now that I've pictured it in my head. Might be a good idea to have keyed slots for the strips to locate into so they're all perfectly aligned as well.
This definitely seems like the way to go. I had my reservations about printing it vertically anyway, since I felt like it'd be hard to do bridging with height changes, even if I supported the fuck out of it.

Thanks once again everyone. You've been pretty patient with me and super helpful. Making things in 3d in Blender is cool, but I never really thought about how things would work in the real world. Printing them really forces me to think about the structural and engineering part of things that I never would have considered.

>>2998943
>can I print the supports first and then print the landscape on top
Only if the nozzle never goes lower than the supports. A flat raft of support material would work, but something contoured wouldn't, the travel moves would just crash into the supports, even if the nozzle had sufficient clearance. If you used a non-planar slicer though it would be a different story.

Anon might be able to pull it off with something like FullControl (https://www.reddit.com/r/FullControl/), e.g. by making a support layer and then a top layer over that which would circumvent the problem of running into the support, but it'd be a hella difficult print to pull off.

>>2998943
you're at the point where you should start printing and see for yourself. the actual printing is cheap as shit, time and the printer are your investments.

also you're printing in PLA and ostensibly PETG for the multi-material, what fucking fumes are you talking about?

also you can use translucent filament as support for itself, it's not like one excludes the other and it's still just PLA

Oh yeah before I forget, I got a survey from prusa today which pretty clearly indicates they want to move to subscription based services. Subscription based "pro" soccer being the most obvious but they had questions about modeling and printers (although not any about actual premium printer features, just an "easy" button). idk, printables trying to be maker world but for a fee seems abysmally stupid to me.

I have it pretty much worked out and I am going to start printing.
Gonna have a little base with a track to use as the base for the mountaiin, each of the strips are printed separately and have fingers that point inward that lock into the track. They're all printed sideways, but at the last few layers, I swap out to a transparent filament.
Slide them all down the track piece by piece and the mountain is pretty much finished. Then I can take that whole piece and drop it into a tray that has the side covers, and the holder for the acrylic sheet.

>the actual printing is cheap as shit, time and the printer are your investments.
I like to have thing planned out in advance rather than throwing things at the wall. I'm used to time being an investment, since rendering shit out takes forever with 3d animation, but I'd rather have a solid plan to work towards over a dead end.

>what fucking fumes are you talking about?
"Apparently" 3d printing puts out a shitload of fumes that you shouldn't breathe over an extended period of time. Whether or not that's true, I'd rather not gamble if it's an easy fix to just vent it out the window.
It's in my bedroom, since that's the only place I have space to put it, so I'm going to be exposed to it regardless, just less since it's going outside.

>>2999028
>key compounds that come off PLA during printing are lactide (a building block of the plastic itself), caprolactam, and propylene glycol. Aldehydes like octanal, nonanal, and decanal are also commonly detected. Although I'd wager it isn't that much. Much worse with ABS (Styrene!). The other problem with 3D printing are fine to ultra-fine particles.
The health effects of which onto humans, to my current knowledge, are still being researched. Not sure what fumes PETG releases.

And no, it's not "Apparently". It does release fumes (along with the cloud of fine/ultrafine particulate matter), this has been subject of research for many years already. It's just not certain if, and how much, effect on the human body this stuff has.

>>2999034
Then yes.
Those fumes. Hence printing enclosed and with a vent. The CC Canvas gets rid of the lid, so there's no venting the fumes. Other anon was acting like it was a non-issue and there were no fumes. In a subject of uncertainty where the margin of error is your quality of life, I'd rather err on the safe side.

Gotta dry it at 80-90C if you want it to be fast. MyTechFun did a video on drying nylons at different temperatures that you might want to take a look at. If you're going to be printing nylons, I'd want to get something equivalent to the Sunlu E2, that can properly dry the filament and anneal the prints.

I have a support ticket but they just recommend inane shit like 'clean the plate' 'check the nozzle is secured/check the extruder's screws'. They suggested the tramming themselves

Any ideas beyond this?

>>2999116
>ran calibration, failed about 5 times on the auto bed leveling step
How is that not instantly a return? I don't have an A1 but you shouldn't be having adhesion issues with the PEI plates, ESPECIALLY the new ones that have craters. You could try unscented aquanet hairspray, but if their calibration is failing how is that your problem? Speak to whoever you bought it from. Also, what filament?

>>2999116
Bambu support kinda sucks because they're either giving you the "This retarded woman just bought a 3D printer for her 9 year old kid" or "Okay, we see the issue, here's a replacement" and there's not really any in-between.
I've experienced both.

My suggestion would to immediately demand a refund. You have 14 days after you receive a printer to get a full refund, and you wanna request that right away, even if it's fixable, you don't wanna get to day 15 and not be able to refund, you know? Plus, it'll almost certainly light a fire under their ass to actually help you. (Do not accept any compensation until you have a fully working printer)

I've literally never had a Bambu printer fail its calibration, so I have no advice really beyond "It absolutely should not fucking do that and there's probably something wrong there".


If you bought the printer from like Bestbuy or Microcenter or whatever, just return it to them and they'll probably just swap it out for you right there and then.

I had a Prusa back in 2019 and it was pretty solid. I've been out of the hobby for a few years and I want to get a Core One L but it seems these Chinese brands have really stepped it up.

bambu is great but their success is due to getting into the market early. I've been rocking a day 1 x1c and have caused more than one a1 purchase but I wouldn't just assume they're better today. I would rather have a tool changer for multi material, the AMS-type systems are a big fault point. I wouldn't not buy bambu, but they're no longer ahead of everyone.

>>2999131
Bambu is in a really strong position. And has really cornered the market on home 3D printing. Their shit is generally good, generally works and has a lot of community support behind it.

I'd say if you just want a 3D printer. Get a Bambu.
If you want specifically a multi-material printer to print toys and gadgets in PLA, get a Snapmaker U1.
If you're an industrial engineer who wants to recommend what printer his company gets. Get a Prusa.

>>2999166
>>2999170
After two years of daily printing I have never had to even think about Z offset on my Bambu P1S. I have no idea how I would even adjust it.

Because the nozzle physically touches the build plate the Z offset is set correctly with a very high likelihood without any need for tuning. Sometimes I get a clump of plastic on the nozzle which interferes with the bed leveling process.

wtf do people use to make quick little edits to stl files? Meshmixer flat out doesn't load, you need a degree in 3d modeling to use Freecad, and everything else needs an account to use.

>>2999214
beefy computer, fusion 360 convert to solid, do your edits, rescale if needed, and hope shit doesn't crash.

>>2999201
Even then, Prusa's support and servicing blows Bambu out the water.
I feel like companies expect a better service than Bambu's "Submit a ticket and wait 2-3 days for a potentially useful reply".
Whilst I'm sure they're offering something more direct for actual businesses, that shit is not cheap, and is almost certainly still very Chinese compared to Prusa where you just talk to a guy.

>>2999136
Can't recommend bambu without mentioning that they have been clamping down hard on consumer freedom, retroactively blocking thirdparty software, and throwing lawyers at anyone who dares oppose them.
If you want something that just works and don't mind being forced into their proprietary ecosystem, then it's fine. I just wouldn't be that comfortable given their tendency to alter the deal after the fact.

>>2999228
I mean, yeah.
But what's the alternative?

>>2999230
Depends on what you need, there's obviously Prusa, but there's also qidi, 22idex, funmat, quite a few others.

>>2999231
I wouldn't say that any printer from china is going to be any more secure than Bambu is.
And printers made in the west tend to be significantly more expensive.

It's a shitty situation, desu. (And it's only gonna get worse)

>>2999233
the issue is more to do with Bambu behaving the way it is rather than security.
Printers shouldn't be connected to the internet anyway.

Alternatively, you could also do it in the slicer with a solid modifier, making it a stacked honeycomb infill with no top or bottom layer.

printed one of those tiny whistles with 0.08 layerheight at 45mm/s and it looks pretty much perfect

>>2999411
I'm guessing when you go slow, it cools along the bridge and kinda creates structure in the air. While going fast will go across fast enough, but the filament is still hot and just ends up drooping. Going slow uses the strength of the cooler filament to stretch out to the point that it can't hold it any more, rather than wet-noodling it across.

>>2999411
Part cooling fans can simply cool a certain number of cubic millimetres per second. Go too fast and you exceed that threshold. Use twin 5015 fans.

Been plucking away at this in the background.
I tried the tray idea I had where they lock in, but quickly decided after that print that it wasn't worth it, and that a channel in the base would be simpler and do the same thing. Also had to thicken the slices because when I had the tray, they'd bend in an arc or forward/back instead of sitting flat against each other.
I also learned that the model and the slices themselves are fucking small. They look super big and chunky in Blender, but when you print it out it really drives home what scale you're working at. Even with calipers next to my mouse for reference, it still seems abstract and larger than what gets printed out.

But yeah, pic related is the result of my last test. I chopped the model up to test the front, and some of the taller bits. Layer height is pretty large just to see how things fit together. I'd like to figure out a way to print some of the base on the side to make the terrain on the border a bit cleaner. The mountainous part isn't too bad, but the plains area is looking pretty shit.
I've got some Flashforge Burnt Titanium PLA coming in the mail along with some transparent filament, so I think by the time that's in I'll be ready to go.

The holes were kind of a problem (though I guess not so much now), but an anon mentioned swapping to transparent PLA for the last few layers to do the same thing, which I think will work better than holes. If it doesn't, I think I can do the holes and not run into any issues now.
And nah, it's going to be a diorama that sits flat like >>2998782

Manual filament swap? I was thinking about just printing thinner clear slices seperately and stacking them together, but all as one print would probably look a bit better. Or at least require less post-processing, sanding the top surface bumps. You could schedule a bunch of filament changes, and print it all in one go.

Yeah too small for a wall I guess. I was thinking if you had a 300x300 printer, you could print 300mm long slices and arrange them on a 300x900mm wall artwork.

I could print separate transparent slices, but I'm gonna just do it manually with swaps. The bright side is that all the strips are the same thickness, so I can just chuck a shitload of them onto the bed, and have the gcode pause at a layer, swap, and it does all of them at the same time. I have 50 slices, a 256x256 bed should be able to fit a good handful of them I think (5-6 for the taller slices, and 15-20 of the shorter ones).
I'm trying to use as much of the space as I have to make as big a model as I can, at least without cutting it up more.

It would be cool to try and make a version that's wall art though. Squash all of the dimensions so it has some depth but not as much. I might give that a try after. It'd be as simple as scaling down all of the slices by whatever value, and maybe altering the base to angle upwards towards the wall for forced perspective.

Yeah if you don't have an AMS, multiple slices per bed is the way to go. You could still do multiple layers and multiple slices all at once, but that would mean going to your printer every 40 minutes to do a manual swap. Actually I'd do the clear layers first, that way it's only ten minutes or so after starting the print and it will finish by itself.

is there a trick for printing delicate parts?
tried printing a mini infinity cube to see if my printer was capable of it but i had to pry open the bottom layer with a knife
or is my z offset just too low?

>>2999514
>or is my z offset just too low?
If you have to pry it off the bed, then probably. I see a bit of what could be elephant's foot, you can tune that out in your slicer, same for first layer flow ratio, but best to stick to the defaults and get the Z offset properly tuned I say.

>>2999516
i calibrated it a bunch of times today and lowered it until i saw the clear inprint of my bed in the prints, it's really hard to get the prints off the bed now
i guess i went too low
ty for the help

I've had an FDM printer for 10 years but mine is finally dying and I don't feel like fixing it anymore. I bought a Saturn 4 Ultra and god damn I have fallen in love with resin printing compared to FDM. But my first request to print something on it is a full-size staff and I'm trying to figure out if it's going to be more of a pain printing in resin or if I should go back to FDM for this one.

Does anyone have a favorite video where a large prop is made from start to finish with a resin printer?

Thank you anon, atm it's only up on Cults3D as the other sites take it down within a few days. "Space marine action figure"

>>2999699
catbox, then link it here/ tg's 3dpg.
probably the best bet for getting anons to find it.

What's the best 3D printer to get if I want to tear it down and learn how they work? I don't care about results, I just want to mess around with it and see how they work.

>>2999769
a voron kit.
instead of tearing one down you build it up.
then you tear it down to upgrade it down the line because you're understanding of the machine makes obvious upgrades for how you use it SO much more obvious.
