| Abstract Scope |
Magnetic Field Assisted Additive Manufacturing (MFAAM) is an additive manufacturing process that employs an external magnetic field in an extrusion-based additive manufacturing technology to fabricate polymeric magnetic structures. The traditional method of magnet fabrication, such as sintering, cannot produce magnets of complex structures. However, MFAAM can print polymer-bonded magnets with complex shapes. MFAAM can produce polymer-bonded magnets, the mechanical and magnetic properties of such magnets remain a great field to explore. In this research using MFAAM, the magnetic field was implemented during the printing of composites comprising Polyamide 12 as matrix and strontium ferrite magnetic particles as filler, at different orientations. The tensile and flexural properties are compared with neat Polyamide 12, composites printed in the magnetic field and without the magnetic field. Finally, by developing polymer-bonded magnets using MFAAM, this project achieved structures with mechanical properties like or even higher than the matrix material.
