As a strategic metal material,titanium metal has characteristics of light weight, high strength, corrosion resistance, etc. It is a necessary material for aircraft manufacturing and space aerospace industries. It is a key material for 3D printing application, and it plays a role in national security and national defense construction. It plays a vital role. With the rapid popularization of computer technology and the wide application of three-dimensional scanning technology, computer-aided design technology and automatic control technology, and the rapid development of materials science, 3D printing technology has been nurtured comprehensively, and it has been promoted to the forefront of the manufacturing industry. The leader of the three industrial revolutions. 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powdery metal and other adhesive materials to build objects by layer-by-layer printing. It has already been used in machinery manufacturing and aerospace. The military and other fields have been more and more widely used, and with the rapid development of this technology, its application areas will continue to expand. Titanium alloy spherical powder, a suitable material for 3D printing, has always been a key link that restricts the development of 3D printing technology and is monopolized by Western developed countries such as the United States, Germany, and Britain.
3D printing has strict requirements on the composition, particle size, and morphology of the printing powder, while the powder produced by a simple physical crushing process in China cannot satisfy the 3D printing conditions. The small batch production mode of small devices also leads to many problems such as low output of various ball type metal powders, discontinuous production, and high cost, which seriously restricts the development of 3D printing technology.
In order to speed up the development of 3D printing technology and break the technological monopoly of western developed countries on the unprepared titanium alloy spherical powders, in 2018, China first discussed and drafted the "Standard for the Determination of the Sphere-Rate of Titanium and Titanium Alloy Powders." Pangang was selected as the member of the industry standard formulation unit, and discussed with the domestic counterparts and drafted the measurement standard of 15 to 150 micron titanium and titanium alloy powder.
