Got a hunch; your model isn't sitting perfectly parallel to slic3r's build plate, so it's trying to interpret the high spots. Try turning supports on, see if it tries to add anything on the bottom.

Volcano is a bit larger heatblock that uses nozzles with longer threads. It supposedly helps printing with both thin nozzles at a reasonable speed and with wide nozzles at very high speeds. You can take a volcano block and install it in an E3D V6 clone with no problem at all. I have a few, haven't tried them yet because I need a different x carriage that will let me move my inductive probe further down.

What's a good low-friction filament? I got an idea that requires two printed parts to slide along each other (not a bearing, but an actual sliding motion). Not concerned with longevity but the actual smoothness of the sliding itself.

I have gotten around 10meters of sample off of them, 2 types, never used them.
The filament surface is super bumpy, precise prints are probably impossible with these. Its filled with magic sauce, i bet they like to clog the nozzle often.
>>
>>1321932
>>1321997
Looks like I figured it out, there were some non-flat faces that were interpreting weirdly and were hard to find; fixed those and it printed fine.

Any hard plastic type material will give a good smooth slide as long as the contact faces are smooth. and if all else fails, you could just spray the fuck out of it with teflon or something

hey guys, i'm thinking of using my 3d printer to print ribs for my rc aircraft wings and i'm wondering how exactly could i make these pictures/vector drawings/whatever into 3d files, anyone happen to know? Here's the website i've been getting the airfoil designs from and the particular airfoil i'm interested in. http://airfoiltools.com/plotter/index?airfoil=hq3015-il
>>
>>1322280
Google 3D printed airfoil, there is some decent stuff out there

Also look at https://3dlabprint.com/ just look at the pictures to get an idea of what to do

Far as getting it into CAD use fusion 360/ onshape / torrent solidworks or inventor and do your best to give dimensions to all your sketches so it makes it easier to alter when something fails or not getting the results you want.
>>
>>1322280
here is a possible solution, though, no matter what, you're probably going to have to learn some CAD software.

>i'm wondering how exactly could i make these pictures/vector drawings/whatever into 3d files

Draw the profile and then extrude

If the section varies along the length of the wing, draw them and use a loft command
>>
>>1322280
Making 3D files from 2D drawings is fairly easy and straight forward if you know how to 3D design. Sounds like you need to step back and learn how to use some modeling software first. I recommend Fusion 360 or Blender. You can import images into both, but I think Fusion 360 is better for dimensionally accurate parts.

I made a horrible mistake.
Decided to save 3 dollars on my purchase and bought generic pla instead of my usual brand, it turned out so bad.
Mine is usually 1kg 340m, but this was 1kg 400m.

It can print at almost the same quality as my usual pla but only when I increase temperature to 205°c and increase extrusion by 15%.

Will that affect my printer in any way? The temperature is fine as I can do ABS as well, I'm concerned about increasing the output of the place through the nozzle.
>>
>>1322576
I find that with different filaments different temperatures are needed - even if they are the same plastic.
For example I have cheap PETG and expensive PETG, I have to print the cheaper one at 195c and the branded one at 225c
>>
>>1322083
Just buy a new nozzle for that size??? Jeez
>>
>>1322592
PETG requires more fine tuning than PLA, I've never had to print place at over 190°c or increase the extrusion before.
>>
I might have an issue with my Prusa i3, but I'm not sure. I've had it for a couple of years by now, and the nozzle has slowly over time rotated. Last night the prints stopped adhering to the bed despite having the proper clearance and bed having an adhesive mixture. What do I do with/about this? I'm hesitant to just twist it (cold or hot) since I don't know exactly how it looks inside and I don't want to strip threads/etc.

Yes, I am aware the extruder head is filthy, the nozzle is clean, though. AFAIK there's no leakage of plastic like in >>1321195 .
>>
>>1322783
is filament even coming out of the nozzle when its heated out and you push it out? if not you should completely disassemble/clean it. Else you should ensure that the clearance is fine using the paper test and that the gears on the extruder are catching the filament.
>>
>>1322798
Yes, filament's coming out of the nozzle - specifically the problem I'm having is that prints will not adhere to the printbed suddenly; it worked fine that morning but then they started curling at the edges/detaching. I'm not sure if the two issues are at all related, but I'm absolutely sure that the print surface is not at fault here. The nozzle distance to printbed should be fine, but I was considering maybe during extrusion it... lifts off, somehow, and increases the distance? I don't know if that's something that's mechanically likely/possible.
>>
Turns out the reason the aluminum block is rotating is because the wires are pulling on it. I don't think there's a way to fix this apart from solidly attaching the wires to the Y carriage, which might be problematic. I also forgot that brass is a soft metal and took of a sliver of my nozzle while cleaning it with a razor blade, whoops.

Neat / 10. Is the brains of your printer behind that screen or is that something else? I also still don't really get why Europeans/etc. have such deep electrical sockets, it makes the plug about 1.5-2x thicker than it otherwise would be.
>>
>>1322969
Honestly man I do not blame you. Airfoils are a bitch to model and you're better off doing it this way.

You gonna shove a square dowel in that hole and have a different profile at the wingtip? And use monocoat or something? That's what it looks like
>>
>>1323008
Sorry for doubleposting but it's a safety thing mostly. If the plug has to go into the socket to reach the contacts, there's a lower possibility of touching the contacts (or the plug when it's touching the contacts) when plugging or unplugging, unlike US plugs.

My prints are generally of small size (<2" / 5cm) so I don't go through a lot of plastic. I use up about one spool per year, and it's looking to be about that time again. Every time I look for filament, it seems that the manufacturer I used the previous year doesn't have what I need in stock, doesn't exist, or has jacked up their prices. I think my progression was Hatchbox -> eSun -> meltINK3D or something similar; what's on the market these days? I don't need any flashy filaments (i.e. woodfill, carbon, glittery, the ones that smell good when you print, etc.), just a plain old 1.75mm PLA filament. It'd be nice if there was some colour variety, but I'd be fine with just black and white. I'm used to paying ~$20/kg but it seems the new "regular" price is $30/kg or so.

Any suggestions/recommendations/things to look out for?
>>
>>1323016
If you want a little bit of variety, push-plastic has 5x200g filament rolls for the going rate of PLA. You can pick the colors, or for a little less, you can get 5 randoms.

>>1323016
Where are you from, there are often good local firms, but they dont always send their stuff worldwide, so a lot of suggestions can be moot.

I second push plastic. I've been buying plastic from them for a few years now and never had any problems. Good prices and they have sales every few months too (have to be on their mailing list to find out about them). Just make sure you order $50+ to get free shipping.

Curious what do you normally print so small?

Pic related is usually the upper limit of what I print, and it's about egg-sized. I don't have a real use for large novelty objects (i.e. game weapons, objects from games, various printed vases... You know, the stuff you see on Thingiverse) so most of my prints are either stuff I've designed myself or small gifts for friends.
>>
>>1323080
Here's a selection of some of the things I've printed recently. The Behelit is still roughly egg-sized and I think everything's to scale based on that - I can say for sure that the crates on the right have a 2x2cm base.

Looking good so far! Keep it up. Hopefully you find something interesting to do with the printed aspect of it. It mostly seems like extra weight without much advantage, unless you do some funky airfoil shape.

>>1323257
No. It's still priced per the kilogram. I only suggested push if you wanted a little bit of a bunch of different colors. If you don't have a need for a veritable rainbow of plastics, then by all means save your money.

Question about printer vibrations.

In regards to printer health (i.e. printer shaking it nuts/bolts loose) and print accuracy, is it better to lock your printer down in place so it can't move at all, or is it better to allow the printer allow your printer to move when it vibrates? Either moving freely as it vibrates with some sort of caster wheels, or dampening the movements with rubber or spring cushions?

What's the best vibration solution?
>>
>>1323800
I remember Thomas Sanlander testing dampers and proving they lead to sympathetic resonance. I would lock it down if you have the option; I don't know if it helps or harms, but when I built my machine I used loctite on the frame nuts and haven't seen any problems with things loosening up.
>>
>>1323800
I've got no evidence backing this up but i think the print quality would be best if you bolted your printer to a really heavy object.
>>
>>1323818
I wonder what would happen if you added hydralic shocks to eliminate the resonance.
>>
>>1323800
>>1323824
I agree with this but haven't tried it. What I did do is I took those half-inch-thick jigsaw foam mats (people use them for garages, kids' play areas, etc.) and built a box out of them, one panel for each side. Not only does it dampen vibration, it absorbs sound AND insulates heat.

other than needing a sock from the cold I can still print fine if I replace my painter's tape a bit more frequently.
>>
>>1324832

With varying success, yes. But it's very easy to fuck up - hold for too long and it bubbles, hold it over a thin wall and it warps... I normally sand the part first and then go over it with the heatgun just enough for the surface to turn from matte to glossy.

Have a more recent one. The ones in the OP are from months ago.

The updated grip is a single print, which significantly reduces assembly time and shaves down print time a bit. Or at the very least allows me to print in 4 hours in a single print which used to take 5 hours across 3 prints.

I also added a segmented optional front part set that triples the available picatinny rail space.

My Prusa i3 clone has developed an issue, where PLA seems to ooze through the threading of my hotend, with plastic oozing down the outside of the nozzle.

I took my hotend apart, cleaned it as much as I could, then reassembled. THE OOZE PERSISTS.

Any suggestions on how to stop this happening? Or is it time to replace my heating block?

Kind of ruins prints when a pea-sized glob of plastic falls onto it every now and then

I think your threads may be (somehow) worn or ill-fitting. I assume you've screwed in the nozzle as far as it will go? I don't know if it's a good idea/possible, but maybe you could wrap the nozzle threads in a couple of layers of teflon tape for extra thickness/sealing. Last (and dumbest, but still possibly working) solution I can think of is leave the extruder on higher than you would print with, cooking/carmelizing the plastic caught in the threads and solidifying it.
>>
>>1325818
>cooking/carmelizing
Would that even stay solid if I kept printing?

Nozzle and throat both in as tight as I could get them. Block is quite old, I've used it for 2 years and changed nozzles quite frequently - chinkshit metal must have sheared as i've adjusted it over time.

Time to order a new heater block then!
>>
>>1325804
>remove nozzle, ptfe tube and any filament
>clean nozzle thread and upper surface
>heat to 100 and remove any plastic left in thread and block
>heat to 200 and screw in nozzle firmly

>feed filament back in a commence test print
>>
>>1325804
You need to make sure that your nozzle is engaging not on the heating block but the other thingy that screws into the heating block as well as the nozzle (when tight there should be a small gap between the nozzle shoulder and the heating block), also, tighten it all down in temperatures that are atleast 20 degrees hotter than your ordinary printing temperature.

Any suggestions on ways i could improve my print quality btw?

Did you measure the diameter of the filament? It might be 1.67 mm instead of 1.75 mm likes it's supposed to be, so that's why you're having to turn up the extrusion rate. Temperature might be able to to down as well, but understand that different materials require different temps. That's why the band for printing temp is 190-220. Use whatever works for you.

I got mine on sale from filastrooder, not that expensive, costs less than a genuine rambo

if you dont want a good printer board then get a crappy smoothieboard clone, replicape if you want to spend even more, or one of the new M7 boards that are coming out.

getting just the trinamic drivers will keep your speeds slow and low microstepping(with interpolation though).
just spend 50 bucks more and get a faster 32 bit printer AND the high accuracy trinamic drivers.

I'm not a shill, just saying that it is a fast, cheap(ish) way to get modern hardware.
If you want to go step by step, get the trinamic drivers for x/y axis, then get a duet with ramps, then get trinamic for the other 2-3 steppers.

How the fuck do you guys keep your filament dry? My ABS sucks up more water than a jewish man drinking pop from a soda fountain. I have a cheap plastic tote with a foam seal around the lip with a reusable desiccant inside, and after using the filament I place it in a food dehydrator for a few hours. My white ABS is so full of moisture that even after leaving it in the food dehydrator over night, it still crackles and pops when I print. Driving me insane. If I had the money I'd buy a vacuum dehydrator.

>counterpoints
Almost as easy to print as PLA, very sticky, good adhesion, temps are not too high. Compressive strength and hardness is better than PLA, after heat treatment its super strong, we used it in sheet metal forming tooling.
>counter counterpoints
Brittle, stickiness can cause print problems, warps, shrinks after heat treatment like any other material.
>>
>>1327064
Because anything I print with infill or any amount of detail that requires retraction moves ends up like garbage. PETG sticks to the nozzle and then that stuck blob rips out the infill lines. I can't get good and clean prints the way I can with ABS. In vase mode it just works, and the result is flexible enough to not break during regular handling.

desu, i'm not sure it really needs those things.
Its a slicer, not a printer manager. you're more than capable of moving the gcode elsewhere, with a method you see fit.

i would prefer they continue to improve its slicing ability, than develop features that are non-essential. Also, the non-prusa slic3r development has essentially ceased.

consider using the slic3r prusa edition, if you were not.

attach the hydraulic shocks directly to the motors/actuators causing said vibrations, attaching them to the base of the unit wouldn't really help, only if the plateform that the printer actually deposits the filament on can be kept isolated from the printer with it autoadjusting the print head in real-time would do anything.

The image compression hides the layer lines but overall it's pretty nice. It is .1mm, the head, the tail, and the [tail end and two feet] took around 10 hrs to print. The head is fucked so I'll have to reprint that but starting a print at night, taking it out in the morning, and starting another print before work, it's moving at a good pace.

Can I rig my airbrush compressor and some valves with a pot to degas resin and silicone?
>>
>>1328099
Yeah. Make something like this with an inlet(air supply), outlet (discharge), and a suction (resin cup). Open the discharge first, then the supply the air, then open the suction. Assuming you made it correctly, the air should get sucked out of the resin via a vacuum. Look up how to make a "venturri air ejector" for more details.

As an FYI, you can also use a similar design to make a naturally aspirated propane jet burner.

No. I swap filament all the time. Especially so I can use up the last little bit of filament on a roll before using a new one. If the printer doesn't retract to a park position on a pause command you can usually git a nobby zit where the pause took place. But otherwise no issues.

interested in why none, what slicer are you using?

I owned a monoprice rebrand of that back in june, if you do upgrades dont get one of those full sdcard adapters, they destroyed my adapter.
octoprint works well with it if you have a cheap netbook or a raspberry pi and for abs/petg you NEED the heated bed mosfet mod.

printing models on the duplicator are easy, make sure you are using a good slicer, not the inferior included slicer(duh) unless you have a rase3d printer
I have been using simplify 3d for awhile due to speed slicing and not having tiny dropdowns for a single setting window, but for long prints the latest cura beta(at the time, small ones are s3d) has printed all the big models in the pic, the right ones are from the duplicator, but have been post processed and painted, blue and gold just had support removed.

post processing can be a bitch, no mater what you use, but on the primer end (needed for painting on some plastics) spray and automotive filler works if you keep it thin(you can also sand it), house primer samples are cheap, but leaves drips due to needing thinning. get a heat gun, petg was a pain for me, but helps with heated bed/ cooling mods

modwise, the zbrace is good, glass bed with pei on one side is optimal, cooler is best if it is semi circular for a ducted fan direct cooling of the hot end from both sides works with any fan.

oh, also driver wise make sure you just use what is provided, the melzi board in there has a fake ftdi chip, if you plug it into a older netbook you may brick the usb connection. then you have to return the printer 2 days before the no questions return ends.

inverted nipples take priority over cloths when being made solid, causing suffering resolve and fill.

those boobs can be a new benchmark for overhangs as well, printed upside down for testing hollow tree supports, they would have been saggy otherwise.


on an other note, anyone know where to find a good non-planar slicer?
the two that I know are a post processing(very dumb) slic3r perl code and a abandoned 5 axis slicer that seems to hate the sin wave I want to test after spending half a day for it to slice the first 3 layers.

H-bot or coreXY for high precision? Or should i go for an entirely different printer type?

coreXY, dual wire gantry or even a darwin gantry.
They say you should avoid H-bots because they introduce an angular momentum to the x-beam.

Oh, I also forgot the thing the ultimaker does.
That works too.
>>
>>1329034
Yeah the ultimaker thingy is really cool what with reducing the weight of the actual moving part to a minimum. I'm a tiny bit dubious with that design though since the movement produced by the motor has to go through so long belts, bars and whatnot, surely that can't be good for accuracy?
>>
>>1329158
could say the same for coreXY, dual wire gantry and H-bot. The belts of those are even longer.
A Darwin gantry doesn't have those problems, but now you are carrying the X-Motor on the Y-Axis.
My Main concern about the Ultimakers system is the sliders on rotating shafts.
All have their pros and cons. The H-Bot issue is the worst I think with that angular momentum

Sure. It's just slow and small. The v1 is a pain in the dick for a few reasons. The v2 extruder is much better.

Just reroute the heated bed wires and add some PEI. I made a front-facing filament holder for all three of mine due to space constraints.

Also, the included SD cards will corrupt over time. If your prints start to layer shift just pull the card, format it, then reload all your gcode onto it.

>>
>>1330143
>all the way up to 210C
That's the normal temperature you should be printing at in the first place - I've never had a PLA I've printed at anything below 200, anything under that simply won't push through my hotend easily / causes skipping at normal printing speeds. I think you need a cooling fan with more airflow.
>>
Am I supposed to use a cooling fan for printing ABS? Searching for an answer leads to both yes and no answers with no real reasoning

I print ABS with mine on and it does just fine
>>
>>1330214
You'll get sharper details with a cooling fan but it can also lead to issues with layer adhesion. It's an individual choice, but I use a cooling fan when I print in an enclosure so that the air blown isn't as cold as it would be without one.

If i need any kind of detail i always go 190C, it's pretty slow, like 40mm/s infill at 0.1mm layerheight but it's worth it for the detail.
>>
>>1330118
I see what you are trying to do there.
I approve.

No, not with ABS. The best thing for it is actually the opposite - a heated chamber. All the expensive Stratasys machines have a chamber like that.
>>
>>1330229
>>1330235
this, temps can go as low as 180 depending on plastic cheapness,
average and high end pla I usually print at higher temps from 195 to 220 for surface matte/ shine.as long as it is over 170 I can print most pla at 80mm/sec.

I never skip steps, just grinds plastic and gets motor too hot.

NEEDS MORE FANS

Especially if your overhang is okay on one side of the print, but not on the other.

Don't use a dremel unless it's a very fine grit, your part will get eaten in no time. If it's ABS, consider acetone vapor bath / brushing it with acetone.

Might be a dumb question, but how do I "fireproof" my prints? I want to order something made out of Shapeway's sandstone material to use as a candle enclosure but i don't want to spend the money only to find out the airflow prevents it from burning properly. Is there something I can apply to my prints that would at least *temporarily* give it fire resistance, i.e. for a minute or two to make sure the flame doesn't go out?
>>
>>1330702
Soak it in petroleum after it's finished printing.
Alternatively coat it in some other flame retardent?

>>1330706
Might try petroleum, hadn't thought of that. I'm looking for the "some other flame retardant", though, that's what I'm trying to figure out.
>>
>>1330663
You can try scraping (similar to wood scraping). I am not sure how much you can use this on a gun, but this is good/fast way to flatten across the layer lines. It also leaves shinny texture and not matt texture you get with sanding.
I mostly use chisel for removing support material and blobs and stuff, and then I use long side edge for scraping.

Petg is supposed to be fire retardant. It depends on your design, but this might work. It might soften, but it wan catch flame as ABS or PLA would.

Based on the magazine, I'd say your bed could do with being a little closer to the nozzle. Not a great deal but just a fraction.
>>
Anet A8 here.
With a 0.5mm nozzle printing at 0.4mm I'm noticing under extrusion. A lot of it. Also the power cable from the PSU to the printer gets noticeably warmer than usual. It barely used to heat up before.

Is my printer incapable of printing at greater than 0.3mm? I've got a 0.8mm nozzle coming from China too.
>>
>>1331222
That's a pretty big layer for the nozzle, it would be like doing 0.32 on a 0.4 nozzle.

Why not a CR-10mini or CR-10S? Good quality out of the box and its having a large community. Also fits your price range and you can get them often cheaper through discounts.

I'm trying to print ABS without an enclosure and have had little success. I've got a few prints to come out, but there was initially bed adhesion issues and then layer adhesion.

I cranked the bed up to 100, but now that my bed is seasoned it seems to stick fine at 82 C.

I printed a few test cubes and they werent bad, but had some splitting on the sides where the area pulled due to shrinking. I tweaked the settings and moved on to a real print: the leveler wheels. Now when I check on the printer instead of layer after layer of plastic, I get this weird sporadic crumbly plastic in the shape of what I want printed. The plastic is stuck to the bed, and the first few layers look fine, but then things get fucky. I printed a go pro mount that was an inch or so high, so I figured ambient temperature shouldn't an issue for these little wheels that aren't nearly as tall and have the radiant heat from the bed to keep them warm.

I occasionally hear a crack or a pop, but the filament is new. Before I go throwing my new ABS in the oven (is that even safe if I plan on using the oven for food later?) I thought I would post my settings.

Cooling is off
brim set to 5mm
all at once print, though it shouldnt matter because I've reduced the print down to a single object until I get things dialed in correctly.

Also, whats a cheap source of glass for making new beds? I had a piece set aside in my garage and it has vanished. I was saving that shit for 10 years because one day I would need it to finally fix my mother's clock face, but decided to use it for my printer instead. The day I finally decide to use that crap it's fucking gone. Really rustles my jimmies.
>>
>>1331280
I the printer to print another test cube and I can see it coming out fine, so I don't think the nozzle is compromised. The only thing I can think of is that the cube prints completely hollow and that somehow the printer is fucking up trying to get the infill down. I guess I'll see what I can do with the infill settings. The wheel creator said to use 0 infill, so I guess I'll see what that does.
>>
>>1331282
You can't really use "regular" glass for 3D printing due to warping and strength issues - what you generally need is borosilicate glass. It's cheap enough, maybe $10-20 on Amazon of the size you need.

If you want to use mirror dont cut up an old one, go get mirrored tiles at the hardware store. They are made to be stuck to the wall with no borders so they have to be tough

Generally keep your layers heights sub 80% of what your nozzle diameter is. So your just at the tip of ok. But now when you are pushing a lot more plastic out have to make sure your extruder can keep up, it also helps to run your hot end a little bit hotter.

But 80% of 0.5 is 0.4, and the power cables are a concern.

>>1331482
If you want to make your own models I recommend starting with tinkercad, it's what I use and probably the most beginner friendly.

If you want to print your models, use Cura to process it and copy it to an SD card. It has some preset quality settings like low, medium, or high.

Once you start to feel a bit more confident you can try fiddling with more settings to improve the quality of your print.

I'm an absolute brainlet too and wasted somewhere between 50-100m of PLA just getting things right.

If you can't understand what needs to be done through written guides then check YouTube.

I printed my first object after designing it using OpenSCAD, and it's mostly fine. Only issue is that it is intended to have spherical endcaps, but OpenSCAD breaks that down into a bunch of rhombuses (probably triangles internally) and prints with about 40 flat sections around each segment -- sort of like a disco mirror ball.

Pointless, when there have been magnetic-connector outlet designs for over a hundred years. No magnet => the contacts don't even get power to them because the spring-loaded thingies behind the outlet don't pull forward to connect. Disconnecting the "plug" automatically safes the outlet so toddlers can shove forks and fingers and tongues in it all they want.

Check your board, check the gauge of wire from the PSU to the board, also if you haven't external mosfet for the heated bed, it draws a lot of power at higher temps and anet is known to start house fires due to the shortcuts they took for the power situation.

Also glass is cheaper to get it "flat" over the cheap metal beds.

As you might see from the picture i ended up going with a lot bigger aspect ratio (the wingspan is still the same 2 meters) than what i first thought i'd go with, i wanted to go with 50 which would have meant a chord of 40mm but i just couldn't get my spars to have a big enough hole for the 3mm carbon fiber rod at the height of 4mm so i ended up going with a height of 4.4mm and a chord of 44mm which gives me an aspect ratio of somewhere around 45 which is completely fine.
I decided to space the spars around 5cm apart which ought to give me nice structural strength without much weight.

At 3DP temperatures, it really shouldn't matter whether you use boro or soda-lime glass. I used to do glass artwork. The temperature to melt soda-lime is around 530C. A piddly 220C isn't going to overstress it, not with the extrusion size that we're generally using (because the heat content just isn't enough). Once you've done the base layer it won't even notice the temperature differentials. If you're heating the bed, it's not gonna care at all.

Depending on your printer you could just store it inside and move it out for printing, that way the bed will be farm for the first layer, just put some gluestick on the bed and i doubt that it'll detach (assuming you're printing with pla) sometimes i but too much gluestick on my bed and the prints are really hard to remove.

I built an enclosure for my printer out of these panels - One for each side, so 6 total. Works great to insulate it and keep it safe from drafts.

Correct.

The piece that goes at the end of the plunger tube is printed with 2mm perimeters and 100% infill, and the Sear should be also though the PLA ones tend to round off after 1,000 shots or so. The ABS ones don't have that issue.

All of the other parts are a minimum of 1mm perimeters and 20% infill.

It's Cura for BCN3D.

There's also really bad blobbing but I think I just need to get fresh filament for that

Can't you just tweak your retraction or something?
>>
>>1333159
>What the hell is going on with your shit
I know, right?

I forgot to mention that my settings have worked perfectly up until the last few prints.

It's GizmoDorks 3mm gray ABS on a BCN3D Sigma. It's not very old and its kept in an enclosure so it isn't brittle and shitty. Retraction is pretty high - 7mm at 70mm/s - but it's always been fine before. Maybe I got a spool that is relatively significantly different diameter from what I had in the past, I dunno.

I'm going to try a print sliced with Simplify3D and see what results I get. I always just used Cura because it worked well enough in the past.
>>
>>1333146
>was able to withstand over 40kg of weight
40 kg tells me literally nothing

How many pascals? How was the stress applied?

I say it's brittle because while it's very hard it's not flexible like PETG.

PLA isn't that brittle unless you're exposing it to a ton of moisture over a really long time. The decent rolls of PLA I'm using are about as durable as plain polystyrene.

I was originally attempting to cast the majority of the parts and I did produce the first 10 of these that way. But once you add pigments to Urethane resins that are above 50A durometer their rated impact resistance (2.2 izod) starts to fall below that of PLA (1.7 izod).

The parts are way bulkier than they need to be in any areas where loads are expected. I ran mine through 2,000 shots before the parts started to flex in spots, so those are the areas I made thicker.

The PLA isn't tasked with providing structure in very many places anyways. There's 10-32 threaded rod taking up the vast majority of the tensile load. I also have a length of it running from the stock to the bottom of the grip.
>>
>>1333162
>Retraction is pretty high - 7mm at 70mm
Do you really have that much backlash in your bowden? Mine is terrible and I use 5.2 - 5.8 at most

What bed temp are you using? Is the printer itself enclosed?
>>
>>1333166
When I first got the printer (used) I dialed in those retraction settings because anything less led to blobbing and pimples on the outside. The bed is at 90 C and the whole printer is enclosed in a high-tech cardboard box.
>>
>>1333163
Yes 40kg tells you a lot, it tells you that the chain was able to withstand a force of around 390N what more can you want? And the stress was applied evenly enough for the chain to not break in the mounting points but in the middle which is good enough for me atleast.
>>
>>1333164
Have you thought about designing a firing system that doesn't use sliding sears and such? They don't really seem all that good for plastics, couldn't you quite easily design a system that uses numerous pivot points and so on? infact show me the current trigger ssytem and i'll design you a better one.
>>

>Yes 40kg tells you a lot

It really doesn't
A few toilet paper rolls with a plank on top of them can withstand the weight of a grown person if they're oriented just right
Does that mean toilet paper rolls are a good building material?
No

PLA has a weird feel to it, it's like it's absorbing moisture and biodegrading right in your hands. I know it won't crumble overnight, I've left a few parts outside under sun and rain for weeks and they're still strong, it just feels different from ABS for example.

If there was an ABS filament that was as easy to print on an open printer like PLA it would be ideal

This image is a little out of date. The current version is heavier, stiffer, and doesn't bother with the trigger return spring. It's just a basic airsoft style sear lever.
The machined version used a sliding plate with a hole drilled in it.

That might actually be too high, if retraction length and speed are too high the hot plastic in the nozzle will separate from the cooler plastic and then you get blobs.

Do deported feeding offers any disadventage over direct feeding ?
>>
>>1333662
Lower weight for the actual moving part, which can actually be a pretty big advantage, other than that there are only downsides really, you get slightly less precision on how you can control the filament, your retraction amount has to be higher for example.
>>
>>1333615
is that only one perimeter, or two?
one perimeter is harder to get a nice surface finish.
might want to consider z-hop.

you also might have too high a layer height.
nozzle diameter?
layer height?

a good rule of thumb, is:
where optimal layer height is the nearest full step layer height
OLH ≈ .8*NozzleDia

if you're using a .3mm nozzle, those errors might start to disappear around .2 and .15 heights.
i get strange layer behavior, if i print too fast, or too cold; the extruder lags too much after speed changes/retracts.
try slower perimeters.
>>
>>1333379
You're not as intelligent as you think you are.
In you current diagram, a trigger pull would be pushing the "sear" backwards. Even if we adjusted your design to work the way you think it would, the "sear" would not drop enough to allow the bolt to pass, it would need too large of a rotation to actually allow the bolt to pass, it would be too slow at the break and the prolonged contact and slow pressure release would cause more wear than his original design.
>>
>>1333665
>you get slightly less precision on how you can control the filament

>>
>>1333673
real current issues with print head weight is:
acceleration before resonance issues occur.

heavy print heads can get into the 70mm/s speeds rather easily and maintain equivalent quality.

a larger issue with moving the print head around is motor steps being visible in the extruded filament.

essentially, if you don't have 1/32 or smaller capable step drivers, for bowden setups, the limiting factor for quality is not the carriage weights.

for prints that require lots of retracts, there wont really be a loss in quality, but an increase in print times.

bowden is really great when you can push the extruder higher than 250c, have a strong extruder motor, good stepper drivers, and lightweight X and Y parts.
i feel that, unless you're breaking into the 120mm/s range, bowden is not worth the annoyance.

It's a form of toggle link. The same kind use for the action of a luger.

It would be annoying to get right, but can be figured out in assembly model using constraints. I don't know when I'll have time to fiddle with the idea but it would work provided you find the right moment angles and distances.
>>
>>1333698
It will have less wear on the sear because it has less friction and the break can be as fine as you please, just adjust the angels to your own liking.

I guess you could compare it to a Luger action yes, please do post your results if you ever bother tinkering with the concept.

>>1333799
Sounds like all he's asking for is a tool that fits these filters specifically so that it will be easy to take them off. A "breaker" could be a little prybar that pops clips loose, or it could be something more like a strap-wrench that fits around a cylindrical filter body. Depends on the shape, size, position, and other-stuff-in-the-way of the filters.

There's no generic answer. You have to look at what's necessary and work from there.

Someone posted a few photos of his grandfather's tool set for working on the SR-71 once upon a time. There were a couple of dozen different wrenches and the only real differences between them and normal off-the-shelf stuff were a few bends in the shafts, or maybe some material milled off, because they needed clearance around other chunks of metal that were always getting in the way.
>>
>>1333806
I get that; what I'm wonedering about is other people's experiences with building custom tools with plastic (if any). He mentioned one of his friends had made something out of wood, so I'm guessing the stresses probably aren't extreme.
>>
>>1333800
Not Luger sear, just the knee joint thingy, an understandable connection to make even thought the basis of operation or the purpose is not the same they look very similar and the concept is quite similar.
>>
>>1333812
Depending on your infill settings, how many surface layers and so on even simple PLA can be quite strong so go ahead, make your boss happy!
>>
>>1333823
I see, good luck figuring out the reset though.

By the way what specifically was wrong with your current sear? I can't figure out why he thought you should change it. His would have even more wear as the bolt tries to force its way past the dropping sear (and forcing the trigger back).

I'm not him but let me explain a bit, in the traditional sear you have the mainsprings force pressing upon the sear at all times and then you have the sear sliding, now you have to remember that friction is force times coefficient of friction. Therefore with the traditional sear design you have all that force concentrated on that one spot at the tip of the sear that is in contact with the mainspring or whatever, no wonder that it'll round out quickly with plastics like PLA.
Now when it comes to the joint mechanism you notice that the sear isn't really sliding against the bolt before being released and you know what happens after it is released? It doesn't have a lot of force pressing on it, or rather there's nothing to keep it in place while the mainspring is pressing on it and therefore there is less friction on the sear surface. Now i presume that there will be more friction in all of those joints and whatnot but i believe that wearing will be very little since it is plastic on metal contact, very little friction and if you want you can even add lubricant on those surfaces.
And that is why i believe that the joint style system is superior for applications like this where we're dealing with materials that aren't very wear resistant and so on, if you had metal parts or tough plastics the system would just be an unnecessarily complicated one.
>>
>>1333851
>>1333869
Oh and also the reset shouldn't be all that difficult to figure out, infact i do believe that it could be quite easily figured out by using only one spring.
