TU Graz engineers create metal 3D printer that uses LED instead of lasers or electron beams

Engineers at Graz University of Technology (TU Graz), Austria, have developed a new metal powder additive manufacturing system that relies on LED instead of laser sources to melt powder. The 3D printer uses a process known as selective LED-based melting (SLEDM), developed by a team led by Franz Haas, head of the Institute of Production […]
