US Gov to explore requiring 3d printer manufacturers and software developers to contain controls to prevent users from manufacturing firearms components
Justice Department officials are turning to the 3D-printing industry to help stop the proliferation of tiny pieces of plastic transforming semi-automatic weapons into illegal homemade machine guns on streets across America.
This is basically how today's 3d printed guns work, but even still the gun isn't good for more then a few magazines afaik. So it's interesting as a way to create a gun that isn't serialized and the ATF can't trace, but it's not durable, and it still requires a good deal of precision engineering/cost, so its not feasible to print a truck-load and sell them for cheap.
The video kind of proves my point. It was janky, he fired <20bullets, and it jammed several times during the demo. Don't get me wrong, it's cool as hell, but yea not very practical for anything and certainly not durable enough to be a viable alternative to CNC/Milling.
