However, unlike the general mold forming method, the three-dimensional printing technology cannot perform magnetic pole alignment on the bonded magnets, so that the bonded magnets The magnetic properties after magnetization are not good, so it is necessary to develop a three-dimensional printing device capable of magnetic pole alignment to improve the magnetic properties of the bonded magnet after magnetization.
