Fabrication of 3D magnets by additive manufacturing would enable another degree of freedom in magnet design. Laser powder bed fusion (L-PBF) is the golden standard of industrial, precision 3D metal printing. But in contrast to binder-based magnet printing, successful L-PBF of magnet micropowders has only rarely been investigated and suffers from process-related crystal structures that need to be improved to increase mechanical stability, minimize oxidation, and suppress columnar crystal growth. Here, micropowder materials design by nanoparticle functionalization may significantly improve the final microscopic and macroscopic properties, thereby contributing to better hysteresis design.
