High Content Nd-Fe-B in Polymer Composite by Fused Depo-sition Modeling.

Fused Deposition Modeling (FDM) is a widespread method in 3D printing for its advantages of being less expensive, rapid, and easy to use. Therefore, the extrusion molding is adopted to manufacture the synthesis magnet powder and Acrylonitrile-Butadiene-Styrene (ABS) particles for the FDM. Compared to the properties of bonded-type magnetic devices, the magnetic properties, the quantity contained, and three-dimensional structure of hard magnetic composite materials are improved; thus, the applications of bonded-type magnets have expanded.
