text: With a 3D printer, Audi Toolmaking has produced a model of the historical Grand Prix sports car “Auto Union Typ C” from the year 1936 on a scale of 1:2. For this purpose, a selective-sintering laser melted layers of metallic powder with a grain size of 15 to 40 thousandths of a millimeter. The process therefore allows the production of components with complex geometries, which with conventional methods could either not be produced or only with great difficulties.
