E-drive housing of Porsche, printed on the NXG XII 600 in only 21 hours. Porsche has deployed SLM Solutions ’ latest metal additive manufacturing system to produce a proof-of-concept E-drive housing.
The NXG XII 600, which is equipped with twelve overlapping 1KW lasers and a build envelope of 600 x 600 x 600 mm, built the 590 x 560 x 367 mm E-drive unit in 21 hours. This component is designed for use on the front axle of a sports car and features a permanent magnet motor with 800-volt operating voltage, delivering up to 205 Kilowatts. The downstream two-stage transmission is integrated in the same housing and is said to drive the wheels with up to 2,100 Newton metres of torque.
