3D printing is one of powder metallurgy processing technology. At present, powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biological, new energy, information and nuclear industry areas and so on, become one of the most active branches of the new material science. Powder metallurgy market in China in 2001-2014 annual compound growth rate reached 21.7%.
3d printing as a most important part of the powder metallurgy molding process, the market space is also in the rapid ascent. In 2017 the global 3d printing used spherical powder consumption has reached more than 800 tons, the estimated consumption years of spherical powder could exceed one thousand tons in 2018.
Titanium powder is the most important metal raw material in 3d printing and is also the highest technical difficulties, in areas such as aerospace, Marine, medical treatment still has a broad market space for development. Qualified 3d printing spherical titanium powder processing is difficult, the yield is low, only a handful of companies can provide relevant products.
Metal injection molding(MIM), a new method of metal processing: combining organic binder and metal powder, using the traditional method same as plastic injection to form the parts. This method enables the production of very complex shaped parts similar to plastic products or die cast products, but with savings in resources and energy, which is very suitable for production in big quantity.
