According to Anthony, the partly plastic ".22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper" fired 200 rounds without any sign of wear and tear. Tuccille takes the discovery in the direction of politically topical gun control. But in my mind, the example of AM technology raises even more questions about patent law enforcement. Will 3D printing be to the Anti-gray-market-alliance what online porn became to neighborhood blue laws?"
