Abstract TA15 titanium alloy powder was prepared by electrode induction melting gas atomization (EIGA) for laser 3D printing. The effect of different smelting power on printable powder production rate, particle size, powder morphology, apparent density, flowability were studied. The results showed that production rate of printable powder and sphericity were improved with the increase of smelting power, and particle size was decreased. When the smelting power was 65 kW, the production rate of printable powder was 62%, the average particle size D₅₀ was below 100 μm, apparent density was 2.731 g/cm³ and flowability was 22.46 s/50 g. Then, powders with particle size of 50－180 μm was laser deposited directly. The surface of printed samples had no macroscopic defects (such as cracks and pores) and the microstructure of TA15 titanium alloy was basketweave organization. TA15 powders prepared via EIGA method had better laser 3D printability.

Key words： EIGA method TA15 powder laser 3D printing powder printability
