Abstract Scope Soft magnetic composites (SMCs), which provide high electrical resistivity with high magnetic permeability, have the potential to create lighter and more efficient electronic devices. With the increasing complexity of these devices, conventional manufacturing methods limit their application. Recent advances in multi-material laser powder bed fusion (L-PBF) additive manufacturing (AM) have enabled the production of more complex SMCs. Prior research has demonstrated the ability to manufacture metal-on-metal SMCs with high permeability and acceptable core loss, but with poor properties for high frequency applications and high porosity. In this work, we demonstrate an optimization study combining design of experiments, multiscale material modeling, CT analysis, SEM/EBSD, and VSM analysis. This research has yielded a pathway for producing highly dense, higher performance SMCs.
