[NBC] 3-D printed gun fires 6 shots — then falls apart - Page 23

post #221 of 440
Hmmm, a very good point was made on here; How would you trace a bullet ack to a 3D printer gun?? If it takes up to 6 shots to break the printed gun, wouldn't each shot cause a complete change in the barrel, resulting in a 'smeared finger print' per say?

Well, if you made the barrel with a printer, the pieces of it that become embedded in the firer would be a dead giveaway. tongue.gif

Actually, now that I think about it, 3D printing a gun's lower receiver would make it easier for the police to track you down than if you just used a normal lower receiver, as 3D printers are not very common.

Bullet tracing is a flawed science and is increasingly less accepted as evidence today.

Well, bullets are often barely recognizable after impact, so they're not going to get much from them.

for the price of a 3d printer you can buy a drill press, a few bits, a jig, and a whole bunch of 80% metal lowers that won't break after a few rounds

edited to fix my typo of while instead of whole

This.

I see how it could be cool to have a 3d printer firearm, but there's much more to it than just printing one out. You need it heat treated as well and it must be of a high grade polymer or aluminum.

You can't anyway. This myth has been debunked at least twice in academia (in Cali no less). You're pushing a projectile through a tube sized such that lands and grooves within the barrel imprint on the projectile... all at and past the speed of sound. Those individual characteristics that one sees in the bore of a barrel do not show up on the projectile because they get smoothed out along the length of the barrel; most rifled barrels have a tapered bore, which get tighter as you get further from the chamber and therefor puts more pressure on the projectile itself.

Let's talk pistols.

The G22 is an example of a 90% polymer frame...Or plastic, if you'd prefer calling it plastic...However, on a pistol, the slide is what gets registered with an FFL.

the cav arms style lower is polymer and available to anyone that can legally own an AR
as for the pistol comment it depends on the pistol
on many, including glocks, the frame is the part that has to go through an FFL. Yes the factory slide and barrel on a glock have matching serial numbers with the frame but they aren't the "firearm" legally
on a ruger mk2 the upper receiver is the regulated piece
on a beretta 92/96 it's the frame
