Abstract: This paper presents the first comprehensive study on additive manufacturing of a high-melting near-eutectic Mo–Si–B alloy by laser powder bed fusion (L-PBF). An overview about the ambient and high temperature material properties of a Mo-16.5Si-7.5B alloy is given. Therefore, the near-eutectic Mo–Si–B alloy was gas atomized and the powder was analyzed. After developing suitable process parameters for the generation of crack-free samples, the microstructure of the L-PBF material was analyzed in detail using SEM/EDS and EBSD analyses. In terms of mechanical properties, the brittle-to-ductile transformation temperature (BDTT) and the creep rate at a potential application temperature were determined.
