摘要

In an effort to simplify power electronicsrnintegration, we explored an additive manufacturing (AM)rnprocess, or commonly known as three-dimensional (3D) printingrnfor fabricating magnetic components. A commercial fuseddeposition-rnmodel (FDM) 3D printer was modified to extrudernpastes of powder materials into 3D structures. We formulated arnlow-temperature curable Poly-Mag paste, which is a mixture ofrnmagnetic powder and a polymer, as a feed material for printingrnthe magnetic core and used a commercial nanosilver paste forrnprinting the winding. After the structure was printed, it wasrncured at 250oC for an hour without any external pressure to formrnthe magnetic component. The electrical resistivity of the printedrnwinding was about three times higher than that of bulk silver.rnThis is because of the low curing temperature resulted in a lowerrndensity than the bulk. The relative permeability dispersion of thernprinted core had a bandwidth up to 10 MHz with a static relativernpermeability of about 10. Both the winding and core magneticrnproperties will be improved by adjusting the feed pasternformulations and their flow characteristics and fine-tuning thernprinter parameters, such as motor speeds, extrusion rate, andrnnozzle sizes.
