Porsche and Bugatti turn to 3D printing for complex or rare parts
Additive manufacturing is starting to gain acceptance among automakers.

Bugatti’s bespoke brakes

In Bugatti's case, the brand turned to 3D printing to see if it could cut some weight from the front brake calipers on the Chiron hypercar. For the production Chiron, the eight-piston calipers are made from forged aluminum alloy, resulting in a component that weighs 10.8lbs (4.9kg). By comparison, the printed version weighs just 6.4lbs (2.9kg) but manages to have a higher tensile strength. Bugatti turned to Laser Zentrum Nord in Hamburg, Germany for the project.
 
Porsche parts
Meanwhile, over at Porsche, 3D printing is being used for a different problem. The company has been building cars for more than 70 years now, and while many of those older machines are still on the roads, not all the old parts are still available. And reproducing them in small batches in the traditional method, with fixed tooling, isn't really cost-effective. As a result, the company has turned to 3D printing.

 

If you're fortunate enough to own a Porsche 959 but unfortunate enough to need a new clutch release lever, Porsche now has you covered. The original part was made from gray cast iron, but Porsche's spares department will now make you a new one using selective laser melting. Porsche says that "oth the pressure test with a load of almost three tonnes and the subsequent tomographic examination for internal faults were passed by the printed release lever with flying colors. The practical tests with the lever installed in a test vehicle and extensive driving tests confirm the impeccable quality and function of the component."
