Audi Toolmaking has developed a 1:2 replica of a 1936 Auto Union Typ C thanks to a 3D printer. This Silver Arrow model stays true to the real deal and was elaborated by implementing selective-sintering laser technology using metallic powder that has a grain size of 15 to 40 thousands of a millimeter.
According to Audi, they are currently 3D printing components made from steel and aluminum that have a length of up to 240 mm and a maximum height of 200 mm.

More than that, the Volkswagen Group currently has 14 toolmaking units in nine countries and they are setting up cooperative ventures to enhance research and development in this domain.
The top priority is the implementation of metallic 3D printing and 3D printing in the sand-printing method.
