Text of Abstract
A new additive manufacturing method coined "UV-assisted direct write"(UADW) has been developed to produce magnets of arbitrary shapes at room temperature [Additive Manufacturing, 22, 343-350 (2018)]. The UADW method involves mixing magnetic particles with a photo-curable binder to create an ink, which is then extruded through a nozzle and deposited onto a substrate. In this presentation, we will describe how the particle loading and consequently the magnetic strength of 3D printed magnets be maximized through understanding and controlling the rheology of highly concentrated suspensions of plate-like magnetic particles.
