Orientation dependence of mechanical properties of selective laser melted (SLMed) Co-29Cr-6Mo alloy was investigated. Columnar grains and fine cellular dendrites were observed along the powder stacking direction. The accumulation of [100] of the γ phase was confirmed when the scan pitch was 0.2mm. The ultimate tensile strength and elongation of the SLMed alloy fabricated parallel to the powder stacking direction were higher than those of the other SLMed alloy, suggesting that the SLMed Co-29Cr-6Mo alloy may possess mechanical anisotropy depending on the tensile direction.
