| Abstract Scope |
Additive manufacturing (AM) attracts much interest in high-tech sectors for fabricating high-performance and complex objects with tailored properties and minimal waste[1]. The challenge for permanent magnets is to fabricate them with a high filling factor, while avoiding deteriorated magnetic properties.
Herein, hard magnetic objects were fabricated using rare earth-based (NdFeB) and rare earth-free (MnAlC) particles embedded in polymer, inks and resin by extrusion- and stereolithography-based AM. The influence of key parameters (particle size and the use of additives in the composite synthesis) on the printability and filling factor of the printed parts was analyzed. The combination of composite synthesis and advanced fabrication technologies showed a new route for fabricating hard magnetic objects with tuned and non-deteriorated magnetic properties[2].
