Introducing metal 3D printing to the world as a viable solution for fully functional firearm prototypes. At http://www.solidconcepts.com you can learn more about the reliability, usability, durability and accuracy of DMLS as a functioning prototype or product, and this gun is a successful demonstration of each of those attributes. Its chamber sees pressure above 20,000 psi every time it is fired proving the material integrity provided by DMLS technology. The small components needed for the 1911 series gun proves DMLS can meet tolerances and accuracy. We're changing people's perspective about what 3D Printing can do and showing the technology is at a place where we can do this kind of thing and succeed. This technology is capable of fully functioning assemblies at full scale.
