Effect of Mn-Zn ferrite powder on the properties of Mn-Zn ferrite formulation for Digital Light Processing

Manganese-Zinc (Mn-Zn) ferrite is a ceramic and soft magnetic material, which can be, used for the fabrication of passive elements integrated in power converters. The main, challenge related to these converters rely on their miniaturization and efficiency, enhancement. Digital Light Processing (DLP) is a potential additive manufacturing, technique to fabricate fine and complex Mn-Zn ferrite components. This paper focuses, on the analysis of the optical properties of the formulations containing Mn-Zn ferrite, powder. Different particle’s sizes (71–1.3 µm) were used to study the influence of the, cured monolayer evolution and the optical properties of the ferrite. We compared, experimental data obtained on formulations with a low content of ferrite particles, (15%.wt) to the results issued from the Mie theory. High solid content (75%.wt) were, investigated to cover the practical applications of DLP and the role of light scattering, was analyzed and discussed in detail for this specific configuration.
