AD3 - ADDSUB

AD3 - Combination of additive and subtractive laser processes for the production of components of novel electric drives.

Laser-based 3D printing processes can produce components with unrivaled freedom of form. This enables, for example, the design of novel compact e-drives for mobility solutions of the future. Maximum performance with low power consumption is achieved in principle by microscopically thin air gaps in the magnetic components. These reduce eddy currents and thus re-magnetization losses. The ADDSUB project is investigating how such hollow microstructures can be optimized for maximum efficiency and manufactured directly in 3D printed drive components.
