The automatic pistol they printed is a Model 1911 45ACP, the public domain, century-old design by John Browning. All of it (except the springs) was made with Direct Metal Laser Sintering (DMLS). Even the rifling was done by the 3D printer. Assembling the thirty-three components of the 3D printed gun took about seven minutes and the use of some hand tools, but the gun was never machined.
According to the company, the over 30 components were made using a laser sintering process in which powdered metals are melted by a laser in layers using a digital plan. In this, a layer of powder is fused, then the printing machine lays down another layer and the process continues. Once complete, the excess powder is removed as are any supporting structures and the component is filed and cold hardened.
