3D printing speeds time-to-market for electroc motors
Using a novel 3D printing process, four founders of a spin-off of research transfer "Additive Drives" at the TU Bergakademie Freiberg plan to increase the performance and efficiency of electric machines. Their main focus is on the copper coil. In future, this is to be transferred directly from the development data to additive production, thus significantly slashing development and test time.

The selective laser melting production process used for this is optimized for the application, as is the copper raw material. "We achieve an electrical conductivity of 100% according to the International Annealed Copper Standard (IACS)", explains co-founder Axel Helm. As a specialist in additive manufacturing, he has brought the 3D printing process to maturity in his research work. Laser melting also guarantees an extremely firm cohesion of the components. All material properties, from thermal conductivity to clamping force, are therefore in no way inferior to classic metal components made of cast steel, aluminum or copper.

The spin-off is supported by the EXIST program of the German Federal Ministry of Economics and Technology at the Chair of Additive Manufacturing of Prof. Dr. Henning Zeidler at the TU Bergakademie Freiberg.
