Abstract
Permanent magnets and methods of making the same are disclosed herein. The permanent magnets include a 3D-printed, i.e., additively manufactured, framework and an infiltrate such that there is a discrete magnetic phase and a discrete non-magnetic phase or two discrete magnetic phases. The infiltrate may provide superior strength, elasticity or magnetic properties.
