The Texas based company Solid Concepts is the first ever manufacturer of a metal 3D-printed firearm. The company is not actually in the firearms business, but one of the worlds leaders in 3D printing. Apparently, Solid Concepts is trying to push the boundaries of their technology application and stir up up a little controversy in the process.
Their new gun modeled from the classic 1911 45ACP design was successfully proven and tested in the video below. The barrel handled the 20,000 psi per shot pressure and fired 50 rounds with good accuracy from 30 yards out. With this design Solid Concepts has made a huge leap forward in the potential of 3-D printing. I am on the edge of my seat waiting for each revolutionary step of this new technology!
