  • Preparation of titanium and titanium alloy powder for 3D printing based on fluidized bed jet milling technique
    Patent number: 11911826
    Abstract: A method of preparation of titanium and titanium alloy powder for 3D printing is based on a fluidized bed jet milling technique. Hydride-dehydrite titanium powder and titanium alloy powder are used as main raw material powder, jet milling and shaping are carried out in shielding atmosphere of nitrogen or argon, and finally high-performance titanium and titanium alloy powder meeting the requirements of 3D printing process is obtained. The titanium and titanium alloy powder prepared using this method has a narrow particle size distribution, approximately spherical shape, and controllable oxygen content.
