  • Publication number: 20240367233
    Abstract: Embodiments of the present invention provide an electromagnet alignment system for AM or 3D printing technology providing improved in-situ alignment of the magnetic particulate material as it is dispensed during deposition to form a 3D shape. In-situ alignment of the magnetic particulate material can be controlled to be unidirectional or multi-directional.

  • Publication number: 20230212709
    Abstract: A compound or complex containing a rare earth element is impinged with a pulsed laser that is so controlled as to photochemically reduce and obtain a rare earth metal (REM). A mixture of REM salts can be impinged using laser light tuned to selectively reduce a particular rare earth-containing salt of the mixture to separate out as its respective rare earth metal.

  • Publication number: 20180122570
    Abstract: 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.
