Re: Why a 3D printed gun?
3-D printing makes it easier to access firearms. If one can buy the metal parts for an AR-15 pattern rifle, being able to create the polymer frame can be of an advantage.
During firing the the 5.56 *(.223) Nato round is rated at a pressure of 62,366 PSI. No idea if the receiver and bolt carrier can be 3-D printed to safely withstand this pressure, since these parts are made out of special steel which needs to have a certain grade of elasticity to cope with these pressure spikes.
Since gun parts are easily accessible in the US, 3-D printing may increase the number of unregistered firearms.
