Image: Porsche 3D-printing achieved a 10% weight reduction compared with the conventional cast housing while doubling stiffness in stressed areas. Porsche announced its first 3D printed housing for an electric drive. The engine-gearbox unit produced using the additive laser fusion process passed all the quality and stress tests without any problems, said the company. “This proves that additive manufacturing with all its advantages is also suitable for larger and hig...

How Porsche Created the World’s First 3D-Printed EV Drive Housing 21 Dec 2020, 14:21 UTC · by 6 photos The feat was made possible by engineers at Porsche’s Advanced Development department who were experimenting with building methods that would result in lighter parts than those conventionally cast. Taking advantage of the structural layout offered by additive laser 3D printing, they increased the stiffness in highly stressed areas, resulting in a housing that is approximately 30% li...
