I don't know of any good way to present this without it seeming like a "drive-by," but the whole concept of being able to reproduce any solid object, much less a gun, using a computer and 3D printer is almost unfathomable. This was science fiction less than 30 years ago.
The company that did it apparently has an FFL, and has approval from BATF for manufacturing firearms, The latest update in their blurb states that the 1911 copy they produced has now shot 1000 rounds with no problems, which is totally amazing.
They also imply that, using their technique, they can accurately reproduce parts as well, and, if I understand their statement correctly, would theoretically be able to make you a new part for your Mars pistol or Webley-Fosbery revolver.
Given this new technology, I am now wondering what new and insane regulations will be coming down the pike from BATF regarding manufacture of handguns.
