| Abstract Scope |
Additive manufacturing of soft magnetic ferrite cores enables the fabrication of complex three-dimensional geometries and integrated electronic components that are inaccessible through conventional manufacturing. Despite the advantages of using Binder jet printing (BJP) for ceramics, achieving high relative density remains a challenge especially for soft magnetic applications, where residual porosity degrades permeability, increases core loss, and undermines the volumetric efficiency of the fabricated component. In this study, powder feedstock characteristics were varied to investigate their influence on sintering kinetics and densification of binder-jetted MnZn-ferrite cores. Powders of differing morphology and particle size distribution were printed, and the resulting microstructures were characterized to establish the relationship between feedstock properties and achievable density. These results identify the densification ceiling and residual pore architecture accessible through powder feedstock engineering and for selecting post-processing strategies such as reactive hydrothermal liquid-phase densification, where nature and connectivity of the pore network directly govern infiltration and phase-formation. |
