| 摘要 | A method for producing a bonded permanent magnet by additive manufacturing, the method comprising: (i) incorporating components of a reactive precursor material into an additive manufacturing device, the reactive precursor material comprising an amine component, an isocyanate component, and particles having a permanent magnetic composition; and (ii) mixing and extruding the crosslinkable reactive precursor material through a nozzle of the additive manufacturing device and depositing the extrudate onto a substrate under conditions where the extrudate is permitted to cure, to produce a bonded permanent magnet of desired shape. The resulting bonded permanent magnet and articles made thereof are also described. | ||||||
