The Bullet That Could Make 3-D Printed Guns Practical Deadly Weapons
47 replies, posted
3D printed guns aren't more viable than pipe guns (which are much easier to make) unless you're using a metal 3D printer, at least with current polymer technologies.
Although I will admit I saw some tests of a steel printed pistol that ran like a dream so there is a point when they become worth the effort.

Metal 3D printers will not become affordable for a long time.

3D guns aren't a problem in America though
3D printed guns (apart from metal ones made through SLS or whatever) are pretty much worthless and you can manufacture much more dangerous firearms with basic tools (See: Aussie submachine guns)

or maybe it's because guns are fun??
clearly though if you like guns you just want to use them to kill brown people/the government and are a violent maniac

[quote]This statute means that you may be violating the law if you change the appearance of the coin and fraudulently represent it to be other than the altered coin that it is.

Tell me, what does that mean in practice? What possible activity for coins do they mean, or what can you think of? (Fired from a gun? :v:)

As far as I understand, you can never really make strong metal things with a 3D printer because of how the object is made. In a 3D printer, the individual particles are laid down one after the other in layers, which makes a very brittle design much like cast iron.
If you want to make a piece of metal strong, you have to heat it up, twist it and bend it, fold it over itself, flatten it, stretch it, and generally work it over and over. It gives a piece of metal that is much much stronger, and won't burst or shatter under stress.

Kinda sorta. You are thinking of Fused Deposition Modelling with the layering thing, which is only done with plastics and resins. Selective Laser Sintering is how you print in metal, which is a totally different process, and can result in very strong pieces (just as strong as pieces made through subtractive manufacturing, IE: CNC machining)
[QUOTE=JoeSkylynx;46420584][QUOTE=matt000024;46420113]I'm more amazed by how nice the gif looks.[/QUOTE]
Probably would be better as a webm[/QUOTE]
In this case no, it's definitely better as gif:
Since this is a monochrome image (with 256 possible brightness values) and gif supports up to 256 colours via its palette, this is completely lossless (but also somewhat large at 2.8 MB).
If you'd use webm, there would be artifacts due to the compression algorithm (but you could have it in colour and it would be much smaller).
Just what we fucking need, more retarded and uninformed hysteria about 3D printed guns.

Please read.
If you intend to present it as anything but an altered coin it is after modification, you are breaking the law.
Basically you can do whatever you want as long as you do not present the results as anything but modified coinage.
Oh yeah, you can also redeem mutilated coins with the mint for value of materials:

People are going to spew whatever bullshit they want. Remember the "ATF Special Agent" who was going on about how an Airsoft rifle could easily be converted to a real machine gun? (And I agree. If you got a real trigger assembly. And a real upper receiver. And a real barrel. And a real magazine. Shit that's practically a whole gun) They don't even bother giving two glances at actual information, they'll just say what they want/believe
Then he proceeded to try and put the magazine into the gun backwards
The whole point of 3D printing is convenience, Home-Made, and cheaper than going out and buying. This is none of that. Re-using spent brass casings is easier and more convenient than this. Cheaper, too. I don't think we'll ever see a fully 3D Printed gun that works as well as even the cheapest piece of junk you buy at a gun shop

I'm sorry I still don't quite understand, and I did (try to) read it. With fraudulent intent they probably mean trying to cheat in some money exchange or?
If my intention was to put coins into a shotgun shell, without modifying the coins in any way except unavoidable damaging them in the process of firing them into a tree stump or in self-defense, would that be breaking the law or fraudulent intent?
It'd be easier just to print a shiv if you wanted to kill someone with your 3D printer.
[QUOTE=Deng;46419068]I'd have better luck cutting a length of PVC pipe, stuffing one end with gunpowder, the other with pennies, lighting it, and hoping I hit something.[/QUOTE]If you did it would end in "OW, WHAT THE FUCK WHY WOULD YOU DO THAT?" because your pennies would have such a low velocity they wouldn't do anything serious. At least you have a PVC club to defend yourself with after they decide to beat the piss out of you for giving them a couple dozen penny-sized bruises.
Actually you could make a high velocity PVC "cannon" by wrapping it tightly in nylon rope, two layers thick. You'd get one shot with it, but you could get some decent velocity out of it, probably enough to launch a dragon dildo (or something) some five hundred yards away.
