The metal pistol made by Solid Concepts, a 3-D printing service based in Austin, Texas, represents a working 3-D–printed version of the famed 1911 pistol originally designed by John Browning. Solid Concepts created almost all parts of the classic gun through direct metal laser sintering (DMLS), an industrial 3-D printing process used to make metal parts in aerospace manufacturing and for surgical implants. (The gun’s springs were made separately.)
“When we decided to go ahead and make this gun, we weren’t trying to figure out a cheaper, easier, better way to make a gun,” said Phillip Conner, DMLS project manager, in a video. “That wasn’t the point at all. What we were trying to do is dispel the commonly held notion that DMLS parts are not strong enough or accurate enough for real-world applications.”
The 3-D–printed pistol proved both sturdy and accurate during mounted and handheld firing tests showcased in a video posted on 6 November. Solid Concepts says it can 3-D print unique gun parts for any “qualifying customer” in five days—a service made legally possible by the fact that the company holds a Federal Firearms License.
