Americans. You are gun experts. What are your oppinions on 3d printed guns? Look at this. New model. Looks like a real one.https://www.youtube.com/watch?v=3-QdXYZLE_0&t=12They figure out ECM (Electro-Chemical Machining) is a way to "carve" the inside of a metal pipe using electricity and saltwater instead of physical drill bits.The Process: You insert a 3D-printed guide with copper wire into a raw steel tube.The Science: When electricity flows through the saltwater, it eats away the metal in a specific pattern.The Result: It creates professional rifling (the spiral grooves that make a bullet spin) inside a hardware-store pipe, making it a functional gun barrel without needing a factory.Also. If the point of guns is to be able to defend agains tyrants or invaders then 3d printing does that job as well as manufacturing.
>>534776210USA is the land of free so if course they are illegal there
>>534776210no 3D print can compare with the MP5
>>534776210I think if you used the 3D prints to make moulds to cast certain parts out of aluminium/brass, cleaned them up with a file afterwards you could probably get close to something decent. Haven't really seen anyone go through and replace the plastic bits with brass yet, I'd be curious how it performed.not condoning anything cough I'm just a metal guy
>>534776210I'm disappointed how many of these are just 3d printed instead of using the 3d printer to aid in casting. it really doesn't add that much more complexity and allowed for much more functional parts. I've used 3d printed to make wax molds and direct printed wax to make some cool molds for casting and composite work.
>>534776210they're illegal in places where they dont like whites having guns, so like 15% of the USeverywhere else they're fine, legislation hasn't caught up or they dont have plans to, so long as they're not being sold or explicitly made for crimes
>>5347762103D Printed guns are based but they are illegal in some of the most populated states like California and New York. Perhaps for a majority of Americans they are illegal. There are no pro-2A politicians here mostly because there are no pro-2A boomers.
>>534776633What about the 3d printed MP5?https://www.youtube.com/watch?v=E6-3btv5B6s
>ECMIs this different from EDM?And can it rifle the barrel? Making smoothbore guns is trivial in difficulty compared to rifled ones.Anyway, about manufacturing your own guns. All but a handful of states permit you to do so, but they must be serialized if you’re gonna sell them.
>>534776943Apparently they perform well and last. I dont know. Its illegal here Im just curious, they look like they are as good as real metal ones.
>>534777713Not at all, there's a reason our government never cracked down on them, you can 3d print a receiver every other part has to be metal.And the more out of spec your gun is the higher chance you're gonna blow your hand off or worse, go see Kentucky Ballistics, guy was nearly killed by a bullet just being a little too hot of a round and blew his .50cal to pieces and went into his jugular.
Brits ban pressure bearing parts, americans label the receiver as the gun. Most warzones ban every part of the gun.So american 3D printed guns are a single plastic part with every other part metal. For a polymer glock, the only printed parts are parts that are already plastic on the factory glock.
>>534776210As an expert, 3D-printed guns are more effective than 2D-printed guns. 2D-printed guns sound good on paper, but in practice they fall flat.
any gun gets copied by hand in afghanistan/pakistanif it can be done there, it can be done here
