Porsche’s 3D printing journey
In addition to the 3D printed pistons for the 911 GT2 RS, Porsche recently unveiled a new bodyform full-bucket seat for its 911 and 718 series. The seat, which is customizable in terms of firmness level, integrates several 3D printed components, including the cushion and backrest surfaces.
“The seat is the interface between the human and the vehicle, and is thus important for precise, sporty handling,” said Michael Steiner, Member of the Executive Board for Research and Development at Porsche. “That’s why personalised seat shells customised for the driver have been standard in race cars for a long time now.”
The innovative seat design is based on a sandwich construction concept, which is made up of a base support made of expanded polypropylene (EPP) and the customizable comfort layer, which is 3D printed from polyurethane-based materials and achieves its tuneable firmness thanks to a lattice structure. The seat’s outer skin is made from Racetex and has a perforation pattern that encourages climate control.
Porsche is also known for using AM for the production of spare parts that are no longer available for vintage car models. For instance, the company is now producing the release lever for the Porsche 959 clutch using 3D printing. In total, the automotive manufacturer says it is producing roughly 20 replacement parts using AM.
