Energy-efficient electric motors are crucial to the progress of electromobility. Soft magnetic materials with a high silicon content, such as Fe6.5Si, offer the possibility of high electrical resistance, high saturation magnetization and comparatively low power losses. However, due to the brittleness of Fe6.5Si, this material cannot be processed using conventional manufacturing methods (such as stamping). By means of 3D screen printing process, this material can be processed through a powder metallurgical processing route. Thus, electric steel sheets with low thickness, high alloying content and high productivity can be realized. We present results of printed and sintered Fe6, 5Si electric steel sheets with thicknesses between 150 and 350 µm. The power loss can be reduced below 35 W kg^-1 at 1000 Hz and 1 T. The magnetic properties of the sheets will be discussed in dependence on the sintering parameters and the powder properties.
