Co-29Cr-6Mo alloy was fabricated by selective laser melting and the microstructures, mechanical properties and corrosion resistances were investigated. Cellular dendrite was formed along the building direction. Mechanical properties of the SLMed alloy builds varied depending on the tensile direction, which was influenced by their microstructure and crystallographic anisotropy. However, the SLMed builts satisfied the standards on the mechanical properties of dental alloys (JIST6115 and ISO22674). The amount of metals relesed from the SLMed alloy build were lower than that that from as-cast alloys. Therefore, the SLM process can be applicable to the fabrication of dental prostheses using Co-Cr-Mo alloys.
