One person, going by the alias “HaveBlue,” imagined a gun.
He didn’t print an entire gun, though that’s a frightening possibility. He printed a “receiver” for an AR-15, which serves as the weapon’s frame, holding all of the operating parts in place. The receiver is also the part of the gun that carries the serial number.
Not only did his partially-homegrown assault rifle not have a serial number, it worked “perfectly” according to HaveBlue, who reportedly fired 200 rounds.
HaveBlue uploaded his digital model to multiple archives, one of which banned gun designs.
As time goes on, 3D printing will become even more affordable and the use of metals will become more common. There’s no telling what this development will do to gun control, but it’s definitely a scary situation.
