3-D Printed Assault Rifle Breaks After Just 6 Shots - Polidicks

It's not an assault rifle, it isn't an assault rifle, that's not an assault rifle. [QUOTE=TestECull;38705372]The amazing thing is that it worked at all. I'da guessed the recoil from a 5.56mm NATO round would have shattered the parts the first time it went off, not the sixth.[/QUOTE] They used a 5.7x28mm upper receiver

[QUOTE=JoeSkylynx;38706061]Gun Caches have been found all around Scotland and Northern Ireland with similar types of firearms. It should also go without mention that several people in the UK have been making [url=http://thehomegunsmith.com/]guides/huge websites about how to make machine-pistols and bolt action rifles.[/url] We had a pretty good discussion on the Firearms Thread regarding this a few days back if you wanna take a look.[/QUOTE] Thanks for the info, I'll take a look. Hardly encouraging though, I still don't get why people feel the need to own firearms.

This could be awesome. Imagine downloading the latest gear onto your computer and printing it out.

[QUOTE=Matriax;38707335]Thanks for the info, I'll take a look. Hardly encouraging though, I still don't get why people feel the need to own firearms.[/QUOTE] why not? guns aren't more dangerous than power tools or cars

[QUOTE=Matriax;38707335]Thanks for the info, I'll take a look. Hardly encouraging though, I still don't get why people feel the need to own firearms.[/QUOTE] Different strokes, different folks. Something like that. I don't get why people feel the need to own a lot of things, but I don't think they shouldn't be allowed to own them just because of that.

[QUOTE=Matriax;38707335]Thanks for the info, I'll take a look. Hardly encouraging though, I still don't get why people feel the need to own firearms.[/QUOTE] It's a hobby for some (like myself) and others like the protection It's not hard to wrap your head around it.

[QUOTE=Matriax;38707335]Thanks for the info, I'll take a look. Hardly encouraging though, I still don't get why people feel the need to own firearms.[/QUOTE] I don't see why people feel the need to own dragon dildos, anime figurines, expensive or older cars, or aircraft. Don't write something off because you don't understand it.

Any firearm (an AR-15 lower receiver is legally a firearm) should require [url=http://www.atf.gov/forms/download/atf-f-5320-1.pdf]an ATF Form 1[/url] to create from a 3D printer, along with the tax stamp, background check, etc. This is the same standard used for 'homemade' firearms.

You only need one bullet to kill someone... He could potentially have killed 6 people with that rifle, which he obtained "legally", without a license... Also if its plastic... Would pass through a metal detector as well... Not the bullets tho. So this could make some trouble in the future i guess. Edit: Well, the whole rifle wasn't printed, but I'm sure they'll do that soon as well.

And no, a polymer AR-15 wont pass through a metal detector because the barrel and most of the internals are still made of metal. An AR-15 isn't exactly concealable either.

[/QUOTE] You don't need a license to buy a semi-auto rifle in the United States. [QUOTE=Nick Lomax;38707598]Also if its plastic... Would pass through a metal detector as well... [/QUOTE] No, it wouldn't. Only the body of the lower receiver is plastic. All the working bits in the receiver are metal, as are the upper receiver, barrel, magazine, pretty much everything. You can't make plastic springs.

And also yes noticed it wasn't whole plastic rifle. Also, AR-15 probably a bit big to conceal yes, but they can print smaller weapons, small pistols etc.

Just wait until we get 3D printers that use plastics that are harder than metal.

You don't need to file an ATF Form 1 unless you want to sell the firearm. Simply building it and using it does not require registration or a background check. And I feel it would be kind of silly to impose this on 3D printed guns, when we haven't ever really had a problem with legal homemade firearms.

If you tried to print an entirely plastic handgun in a 3D printer in any caliber above .22lr, it's bound to fail after only a few shots. You're more likely to blow off your own hand than anything else.

If it were possible to 3D print a fully plastic pistol, it would be possible to conventionally build a fully plastic pistol.

[QUOTE=ButtsexV3;38707709]that only applies if it's an NFA weapon, like a short barreled rifle[/QUOTE] Edit: Nevermind, you're right. Form 1 is for NFA weapons. There's another form for registering a weapon with the intent to sell it. This one is only needed if you plan to sell the gun to another individual. Gun laws are stupidly convoluted.

[QUOTE=mugofdoom;38707737]I believe the Form 1 is mostly for people who are not FFL's building firearms that they wish to register with the intent to sell and whatnot. It's entirely optional though if you are not intending to sell it.[/QUOTE] if you decide later on down the line to sell it you can still do that, you just can't make it specifically to sell it if you're building specifically for resale you have to get an FFL

You're right. I haven't looked into these laws in a while. I'm a little rusty. Fact of the matter is, you don't need a Form 1 or any other form to build a legal rifle or pistol. Legal being barrel over 16 inches if it's a rifle, no foregrip if it's a pistol, can't shoot 40mm grenades, and isn't full auto.

[QUOTE=Paul McCartney;38705659]Firearms are kinda easy to make. That's why there's so many.[/QUOTE] You've already got a firearm if you've got two hands, a hammer, and a bullet.

I want a 3D printed BAR. 20-round fully automatic M1 Garand, and the only gun on my wishlist besides a barret I have yet to get.

[QUOTE=Zorus;38708520]You've already got a firearm if you've got two hands, a hammer, and a bullet.[/QUOTE] No, not really. Have fun trying to set off primer with a hammer. Zip guns may be simple, but weapons good for more than one shot or more than ten feet of distance require some pretty complicated stuff. Look at an exploded diagram of a handgun or an assault rifle- there's a lot of very fine engineering, even on relatively simple weapons like Kalashnikovs. Even when 3D printing becomes viable, there will still be a lot of parts that will need to be manufactured conventionally. At the very least, the bolt, barrel, sears, and springs will have to be steel.

Have fun picking shards of brass and plastic out of your hands.

would probably work a lot better with metal stintering machine, but those are in an earlier state than 3D printers, and are still really expensive.

I guess this could be useful as an assassination tool or something, a disposable gun would come in quite handy I'd believe.

[QUOTE=Furioso;38706229]so if you really wanted to, you could 3D print a handgun or something, kill someone and then just melt the weapon down to get rid of the evidence? that concept is kinda scary [editline]4th December 2012[/editline] I mean, I guess you could do the same with a metal firearm but it's way easier to melt plastic than metal[/QUOTE] Only the lower receiver, in this case, was made of plastic. Everything else on the gun was purchased and is comparable to manufactured goods (because, well, they are.) I hope people realize that this is not a new concept in the world of firearms. Polymer receivers have been available for AR15s for quite some time, and Glocks, for example, have a plastic lower receiver. The lower receiver doesn't even do anything other than house the trigger mechanism, the actual working bits are in the upper receiver and as far as I know no one has come up with one made out of plastic.

[QUOTE=Trunk Monkay;38708704]You want to make a fully automatic rifle chambered in 30-06 out of plastic? Have fun picking shards of brass and plastic out of your hands.[/QUOTE] when they switch to metal

In time it will get much better, what can you expect from very new technology, it's only going to get better and better.
