Melting is carried out in crucible, obtains titanium alloy melting liquid；
2) titanium alloy melting liquid continues to refine 40~60 minutes after being heated to 1600 DEG C~1650 DEG C；
3) after the completion of refining, high-purity argon gas is filled to powder by gas-atomization furnace, alloy molten solution is atomized with high-purity argon gas, through height
Fast argon gas blowing atomization, obtains titanium alloy powder after cooling.
9. the atomization production of 3D printing titanium alloy powder according to claim 8, which is characterized in that the blowing mist
The argon pressure of change is 0.8MPa~1.2MPa.
10. the atomization production of 3D printing titanium alloy powder according to claim 8, which is characterized in that the step
3) after blowing atomization, drying and screening step are also carried out.
