3D gun printing

[popeyespappy]

All you need to make the same lower receiver out of metal is an aluminum block, a drill press, a cross slide vice, a few bits and those plans. You don’t have to be Tony Stark either, but someone that knows what they are doing could easily turn one out in a day.

the printer can produce 2-4 of the same parts in 7 hours - which is faster.
the material (plastic) is also cheaper and nott as easily dedectable.

The technology to print a functioning semiautomatic center fire rifle without the use of metal parts does not exist at this point in time. At least not on this planet. At the very least it would require one of these



this stuff



a gas tube



and a whole bunch of springs







All made out of metal.
