Crazy Shit: World’s First 3D Printed Metal Gun

Have you already thought about getting a 3D printer for christmas?

This is the stainless steel handgun that was 3-D printed by the guys at Solid Concepts in Texas/USA using a direct metal laser sinistering (DMLS) technique.

Per Wikipedia article about DMLS:
The DMLS machine uses a high-powered 200 watt Yb-fiber optic laser. Inside the build chamber area, there is a material dispensing platform and a build platform along with a recoater blade used to move new powder over the build platform. The technology fuses metal powder into a solid part by melting it locally using the focused laser beam. Parts are built up additively layer by layer, typically using layers 20 micrometres thick. This process allows for highly complex geometries to be created directly from the 3D CAD data, fully automatically, in hours and without any tooling. DMLS is a net-shape process, producing parts with high accuracy and detail resolution, good surface quality and excellent mechanical properties.

Apparently both the cost of materials and the amount of electricity used during the process are astronomical, so don’t expect some militia to be printing their own killing arsenal anytime soon!
