Printing soft magnetic material Proto-pasta composites using Magnetic Field Assisted Additive Manufacturing (MFAAM) significantly increases susceptibility. Samples printed in different magnetic fields exhibit anisotropy in magnetic properties.
Three different samples of soft magnetic material Proto-pasta, a composite of iron and polylactic acid (PLA), were printed in the presence of a magnetic field and then measured using a vibrating sample magnetometer (VSM) to inspect the effects printing in a magnetic field has on the samples' magnetic properties. Multiple hysteresis measurements were taken with respect to the field angle for each sample printed in various fields to observe the changes in hysteresis loss and susceptibility. The Fe/PLA composites printed using Magnetic Field Assisted Additive Manufacturing (MFAAM) displayed a susceptibility approximately twice as large as the composites printed in zero field. Through varying field angle VSM measurements, the inspected susceptibility also displayed anisotropy, having a magnitude 2.7 times larger when measured along the print field.
