During WW2, people in Poland mass produced guns out of their bedframes. If you want to make a gun, you need the exact same things as you needed then. 3d printing makes the easy to manufacture parts, you still need the steel ones that aren’t printable. And if you have those, whether you print it or yank a pipe from your bed, it’ll be just as lethal. Not mentioning slamfire shotguns which are a pipe with a nail inside. You can’t control that shit, people will always get one if they want to.
