Abstract Scope |
Soft magnetic composites (SMCs) are widely used as magnetic cores in power generation and electric motors. However, traditional manufacturing techniques, such as the press-and-sinter process, are time consuming, expensive, and limited by complex shape designs. Additive manufacturing (AM) provides more design flexibility and requires minimal end finishing. We have developed ‘NanoSLS’, a slurry-based additive manufacturing process in which a slot-die coating system is incorporated into a laser powder bed fusion (L-PBF) machine for the deposition of nanosized particles. A custom SMC ink that contains amorphous core-oxide shell nanoparticles is used to achieve better magnetic and mechanical properties. Rheology tests are conducted to determine the optimal coating window for the SMC ink in the slot-die. On top of the benefits offered by L-PBF AM processes, the NanoSLS process requires less feedstock material, generates less waste, is easier to operate and easy to scale up for mass production. |
