In this article, we use a factorial design of experiments to develop a three-way relationship
between the 3-D printing parameters, the microstructural characteristics, and the hysteresis
loss of binder jet printed iron silicon. Subsequent analysis of variance is used to validate the
hypotheses between the printing process input factors and the output factors. The input
factors in this work include the sintering temperature, the addition of boron, and the silicon
content in the starting powder. The magnetic output factors of the printed iron silicon include …

In this paper, the hysteresis loss characteristics of 3D printed iron silicon samples are
compared with soft magnetic composite material. Design of experiments is used to evaluate
the effect of printing parameters on hysteresis loss. Printing parameters considered in this
paper include the sintering temperature, the addition of boron compound, and the silicon
content in the starting powder. The addition of boron in the 3D printing process of iron silicon
samples is shown to reduce the intrinsic coercivity and hysteresis loss.
