摘要

•Binder jetting technique was employed to fabricate NdFeB isotropic bonded magnets.•Printed magnets were infiltrated with low-melting point eutectic alloys.•Magnet density was improved from 3.3g/cm3 to 4.3g/cm3 with infiltration.•The intrinsic coercivity Hci was enhanced after diffusion of NdCuCo and PrCuCo.
