Abstract: This paper presents a comprehensive study conducted to optimize the selective laser melting (SLM) parameters and subsequent heat-treatment temperatures for near-α high-temperature titanium alloy Ti-6Al-2Zr-1Mo-1 V (TA15), which is widely used in the aerospace industry. Based on the surface morphology and relative density analysis, the optimized process parameters were: laser power from 230 W to 380 W, scan speed from 675 mm/s to 800 mm/s, scan spacing of 0.12 mm, and layer thickness of 0.03 mm. The effects of the laser power and the layer thickness on the phase constitutions, microstructure.
