Industrial 3D printing accelerates electric car industry

voxeljet 3D printing technology for production cast parts for electric-mobility. As key suppliers of the car industry, many foundries are under threat due to the current growth in e-mobility. 

The reason is, that the demand for castings for an electrically powered vehicle is significantly lower than for a conventional combustion engine. 

To improve the performance of their electric engines, the customer of the Chinese foundry MeiMai Fastcast Suzhou Co. Ltd turned to voxeljet. The mission: The first generation of their electrical engine did not meet the demands of various passenger cars.

Cost efficiency, wast reduction, lower risk in mold revisions

Another advantage of the 3D printing process, besides the rapid production of the molds, was the cost efficiency for small batches.

In addition to the rapid realization of the engine parts, MeiMai Suzhou was able to improve its motor performance by intelligently optimizing the designs. “The durability of the components can also be influenced. As a next step in the housing development, we will also tackle weight reduction through topology adjustments such as the position and height of the outer reinforcing ribs,” says Tianshi happily. “Thanks to 3D printing, e-mobility is a real opportunity for foundries!”
