Volkswagen Toolmaking has recently been expanded from 460 to 3,100 square meters so give its toolmakers, designers, developers, and researchers more space to collaborate on new technology faster. A goal of the project is to use 3D printing technology in series production at the site. In addition to the world's first brake caliper shown in the video below, the VW research facilities have 3D printed wheels and other parts for the Audi lunar quattro moon rover, parts for electric race cars, and rare, discontinued parts for vintage vehicles. Volkswagen had been relying upon the Selective Laser Melting Process (SLM) where materials such as steel are in the form of a fine powder that is applied to the areas where the component is to be made and then melted by a laser. The melted powder hardens and forms a solid layer of material that is combined with other layers to form a three-dimensional object. A new collaboration with printer manufacturer HP and GKN Powder Metallurgy has integrated the Binder Jetting process into manufacturing production to supplement the SLM process. The Binder Jetting process makes components layer-by-layer and fuses them using metal powder and binding substrates (binder). Heating the component by pressure yields a formed metallic part. Volkswagen says that the Binder Jetting machines make 3D printing metallic parts not only simpler; but also faster! This advance in technology has spurred the drive to move into the production of 3D printed metallic parts as the increased construction rate has made it cheaper than traditional manufacturing and other 3D metal printing technologies. Bugatti is another member of the Volkswagen Group that is instrumental in advancing innovative future-oriented technologies. It has developed the world's first brake caliper made by additive manufacturing, namely an 8-piston monobloc model. The French super sports car brand is also the first series producer to use titanium and at the same time produced the largest brake caliper in the automotive industry. Bugatti's newly developed 3D printed brake caliper uses an alloy that appears primarily in aeronautic and aviation applications and features especially high strength and performance properties. Compared to previous aluminum components, which are installed in cars like the Bugatti Chiron, the printed titanium brake caliper could save considerable weight and would also be more robust.
