Descrição: Magnetic filaments for fused deposition modeling, 3d printing, were produced by depositing Nylon12 onto SmCo5/Fe exchange coupled nanocomposites powders by liquid-liquid phase separation and precipitation. The produced filaments have a high coercive filed of 1 T at 300 K. The usefulness of these types of filaments in the production of 3D printed magnets with special stray field geometries was investigated by implementing an evolutionary algorithm capable of generating the appropriately shaped magnet. The desired, calculated and magnet stray field geometries were compared and found to be reasonably similar. [Display omitted] •Nylon coated SmCo5/Fe nanocomposite powders.•Magnetic filaments (up to 24% SmCo5/Fe) have high Hc and Mr.•3D printed magnet stray field is optimized by genetic algorithm based on FEM calculations.
