Abstract 3D printing is a new type of manufacturing technology, which is widely applied in the field of aero‐
space, medical treatment, automobile, ships.Titanium alloy is an important part of metal 3D printing system due to
its excellent properties such as light weight, high specific strength, good corrosion resistance and excellent biocom‐
patibility. The performance requirements of titanium materials and main preparation methods of powder of 3D
printing were briefly described. The characteristic of GA and PREP preparation technique were compared, and the
reason for the difference of GA and PREP preparation technique were explained emphatically. At last, research
directions and application prospects were expounded.
