OpenSLS - Selective Laser Sintering 3D Printer by Andreas Bastian

Andreas Bastian and his team have been working on a 3D printer that utilizes selective laser sintering technology (SLS). He built it for under $15,000 and it can print in a variety of different materials. It is part of a RepRap project called OpenSLS, and they have made significant process. The powder handler is constructed using a laser cutter and some 3D printed parts.
