The Solid Concepts Browning M1911 replica, version 2.0, will be composed of 34 [[Inconel 625]] components, (not including grips). The two carbon-fiber filled nylon 12 grips were also 3D printed. Unlike early 3D printed plastic guns, the barrel of the 1911 was rifled. None of the parts were machined during production, and assembly took less than seven minutes once the parts had been filed and hardened.<ref>[http://www.gizmag.com/worlds-first-3d-printed-gun/29702/ Solid Concepts manufactures first 3D-printed metal pistol], Gizmag, November 8, 2013.
