Abstract
UV-cured 3D printing technology had become more and more popular due to its rapid printing speed and high molding accuracy. However, for ordinary Direct-ink-writing (DIW) printers, though there were widely materials can be used, but they cannot be quickly printed and molding accuracy was much low. Therefore, a simple method combined UV-cured and DIW was summarized in this paper, before DIW the mixed slurry (FeSiB and Epoxy resins soft magnetic composites without photoinitiator added) was pre-curing by UV for some time to a semi-cured state, the rheological properties of the slurry were investigated and the magnetic, mechanical properties and micromorphology of printed products were studied. Compared with the printed products without UV pre-curing, the coercive force (Hc) was reduced by 20.36%, the elastic modulus increased by 34.41%, and the insulating coating after UV pre-curing was more uniform, with no obvious defects.
