Additive manufacturing (AM) is a production technology attractive for various sectors such as aerospace, biomedical, and automotive. The advantages are various, including being able to create objects with complex geometry and through a careful study of topological optimization, reduce the weight while maintaining mechanical performance. The aim of the present work is to study the feasibility of producing ferromagnetic materials using AM technology for electrical application such as rotor for electrical machine or electromagnetic devices via Laser Powder Bed Fusion (L-PBF). L-PBF is shown to be effective to produce soft magnetic materials (SMMs) such as FeSi2.9. Dedicated test samples with various geometries have been manufactured for evaluating the electrical and magnetic performance under as-built conditions and after annealing.

Abstract

Additive manufacturing (AM) is a production technology attractive for various sectors such as aerospace, biomedical, and automotive. The advantages are various, including being able to create objects with complex geometry and through a careful study of topological optimization, reduce the weight while maintaining mechanical performance. The aim of the present work is to study the feasibility of producing ferromagnetic materials using AM technology for electrical application such as rotor for electrical machine or electromagnetic devices via Laser Powder Bed Fusion (L-PBF). L-PBF is shown to be effective to produce soft magnetic materials (SMMs) such as FeSi2.9. Dedicated test samples with various geometries have been manufactured for evaluating the electrical and magnetic performance under as-built conditions and after annealing.
