Functionalizing magnet additive manufacturing systems with in-situ magnetic field source

CMI technical publication on functionalizing permanent magnet additive manufacturing systems with a magnetic field source. The field source was modeled, designed, prototyped and tested on an existing table-top commercial 3D printer.

Ce-based gap magnets match high-temperature performance of neo

CMI research at Ames Laboratory Achievement showed that at certain temperatures a cerium-based magnet matches the energy product of and exceeds the coercivity of neodymium permanent magnets
