Current situation and development of 3D printing materials for metal at home and abroad

In this paper,the basic concepts and procedure advantages of 3D printing technology of metal were briefly introduced. The types,applications and manufacturing processes of 3D printing materials for metal at home and abroad were summarized. The development trend of 3D printing materials for metal was analyzed. The results showed that aluminum alloy,titanium alloy and iron-based alloy in the application of 3D printing materials for metal developed rapidly,and traditional 3D printing metal materials and composite materials need to study emphatically.
