We have seen some 3D printed cars in the past and they are often not what most would consider attractive cars. Audi Toolmaking has 3D printed a new car and it is a dead sexy little ride called the Auto Union Typ C that is an exact model of the “Silver Arrow” Grand Prix sports car from 1936. The car was 3D printed using metal and sand.
The car was made using a selective-sintering laser that melted layers of metallic powder with grain size of 15 to 40 thousands of a millimeter. This printing process allows Audi to make components with complex geometries that couldn’t be made with traditional methods of construction. The printing process can make items that are as large as 240mm long and 200mm high.
“We are pushing forward with new manufacturing technologies at Audi Toolmaking and at the Volkswagen Group,” stated Prof. Dr. Hubert Waltl, Audi’s Board of Management Member for Production and Head of Toolmaking at the Volkswagen Group. “Together with partners in the area of research, we are constantly exploring the boundaries of new processes. One of our goals is to apply metal printers in series production.”
