China3D printingNet December 21, Germany3D printingMachine manufacturer SLM Solutions in its recently released NXG X11 600 3D printingA proof-of-concept E-shaped drive housing was printed on the system for Porsche.
3D printingThe shell consists of an integrated two-stage transition and electric motor, designed for the front axle of a sports car.
Falk Heilfort, Porsche Powertrain Development Engineer, said: “This new manufacturing technology is very helpful to us technically and economically, especially in the development phase and special small-batch production as well as prototypes of racing cars and classic parts.”
Porsche’s electronic drive housing was printed on the NXG X11 600 system within 21 hours. The picture comes from SLM solutions.
SLM Selective laser melting3D printingtechnology
SLM Solutions is an expert in the development and production of selective laser melting (SLM) additive manufacturing systems. SLM uses a high-power laser to melt metal powder along a predetermined path, which can quickly create parts with complex shapes. In addition to the recently launched NXG X11 600 3D printingIn addition to the system, the company’s current machine products also include SLM 125, SLM 280, SLM 500 and SLM 800 3D printingsystem.
SLM released its large format NXG X11 600 on Formnext Connect in November, which is custom-designed for mass production of large parts. The machine is equipped with 12 overlapping 1 kW lasers, which can be operated simultaneously and combined with a 600x600x600mm housing, which can easily produce large quantities of spare parts with a thickness of 120 µm. The printing system also has a variable beam spot, two-way recoating, laser balance and optimized air flow to increase productivity.

3D printingElectronic drive housing
SLM has partnered with Porsche’s advanced powertrain engineering department, which is seeking to explore the potential for the production of auto parts (such as E-drive housings, cylinder blocks and cylinder heads) through additive manufacturing.
Using LMG X11 600, SLM printed a complete conceptual E drive housing for car manufacturers in just 21 hours. A permanent magnet motor capable of providing 280 hp and a downstream two-stage transmission are integrated in the housing to drive the wheels with a torque of up to 2100 Nm.
A grid structure is printed on the shell to optimize the topology of the part and reduce its weight. SLM3D printingIn addition to improving the rigidity of the parts, the technology can also improve the functional integration of the cooling channels. By integrating parts into a single E-drive housing, part assembly time is greatly reduced, and the overall part quality has also been reportedly improved.
Ralf Frohwerk, Global Business Development Leader of SLM Solutions, said: “We are very pleased to cooperate with innovative companies like Porsche. Extensive use of additive manufacturing technology for true mass production.
We strive to take this big step towards the full industrialization of Porsche metal additive manufacturing. “

3D printingTechnology and cars
Porsche pair3D printingNot unfamiliar, he has previously worked with machine tool manufacturer TRUMPF and auto parts company MAHLE to provide the engine for its flagship 911 super sports car3D printingpiston. Laser metal fusion (LMF) technology adds 30 horsepower to the engine and reduces the weight of each piston by 10%.
Prior to this, the car manufacturer had already started printing parts for its rare and classic cars and announced that it would carry out3D printingIndividualized bucket seats for prototypes on European racetracks.
Elsewhere in the automotive sector, the startup Czinger will launch its first model in 20213D printingSupercar 21C, and car manufacturer Continental AG recently installed Stratasys Fortus 450mc FDM under its Additive Design and Manufacturing (ADaM) capability 3D printingmachine. Karben Center, Germany. The printer will be used to produce functional prototypes, final parts and fixtures and fixtures for the company’s own production line.
