Ti-6Al-4V alloy has a high strength-to-weight ratio, high corrosion resistance, along with good fatigue and creep properties. Developments and advances in additive manufacturing have created new horizons for enhanced processing and manufacturing of Ti-6Al-4V alloy. A major challenge of the additive manufacturing techniques is the inability to achieve identical microstructure and mechanical properties in different build orientations. In this work, the microstructure and mechanical properties of additively manufactured samples were studied and compared with traditionally processed samples. Rectangular samples were printed using the Renishaw’s AM250 selective laser melting system. The samples were fabricated in three perpendicular orientations. Tensile test specimens were machined from the printed samples and the fracture toughness specimens were tested as fabricated. Effect of build orientation on the microstructure and mechanical properties of selective laser melted Ti-6Al-4V samples was studied.
