Abstract
A system for direct writing a conformal or free-form magnet includes producing a magnetic ink compound by mixing an photopolymer base and a magnetic material powder, extruding a layer of the magnetic ink compound through a nozzle on to a target substrate to form a layer, soft-curing the layer by exposing the layer to a first light, repeatedly extruding a layer and soft-curing the layer, then post-curing the magnet by exposing the magnet to a second light and an elevated temperature.
