Biological material 3D printer spraying head alloy powder and preparation method

The invention relates to biological material 3D printer spraying head alloy powder and a preparation method thereof. The powder is composed of the following components of, by weight, 3.5-4.5% of Al, 1.0-1.4% of Zr, 2.5-3.5% of Cr, 13-15% of Mn, 19-21% of Si, 1.8-2.2% of Fe, 2.2-2.4% of Cu, 0.1-0.2% of Ce, and the balance Ti and unavoidable impurities. The powder is spherical, the particle diameterD50 is 80-90 [mu]m, and the particle diameter D90 is 180-200 [mu]m. The loosen density of the powder is 3.25-3.35 g/cm , and the powder liquidity is 12-18 s/50g. The tensile strength of a titaniumalloy can reach 1100-1200 MPa, the pressure-resisting capacity is high, reciprocating pressure circulation can be borne, the elongation at the room temperature can reach 20% or over, and high-temperature-resisting and anti-corrosion performance is excellent. The powder liquidity is good, and the biological material 3D printer spraying head alloy powder and the preparation method thereof are suitable for laser rapid fusion ad
