Beschreibung
Zusammenfassung:	A method for producing a bonded permanent magnet by additive manufacturing, comprising: (i) incorporating components of a solid precursor material into at least one deposition head of at least one multi-axis robotic arm of a big area additive manufacturing (BAAM) system, the components of the solid precursor material comprising a thermoplastic polymer and hard magnetic powder; said deposition head performs melting, compounding, and extruding functions; and said BAAM system has an unbounded open-air build space; and (ii) depositing an extrudate of said solid precursor material layer-by-layer from said deposition head until an object constructed of said extrudate is formed, and allowing the extrudate to cool and harden after each deposition, to produce the bonded permanent magnet. The resulting bonded permanent magnet and articles made thereof are also described.
