摘要	In this paper, a soft magnetic composite (SMC) material, FeSiCr, is analyzed for its beneficial electromagnetic properties and unique 3D formation capacity, which endows a very high potential to become the material for electric motor fabrication by 3D printing technology adopting high temperature selective laser melting (SLM) process. A microscopic and spectroscopic experiment performed on FeSiCr after SLM process showed that FeO is the oxide layer responsible for the unique advantages of this material. Furthermore, FeSiCr is proved to have lower core loss and eddy current loss at high frequency via the comparison analysis between FeSiCr and silicon steel sheet, a popularly used material for electric motor construction.
