Abstract：To decrease the development cycle of blades of gas turbine, the present research situations as well as the application both at home and abroad of metallic three-dimensional printing technology used in the fields of rapid manufacture and the repairment method of laser cladding technology for gas turbine blades are elaborated on the basis of summarizing the main three-dimensional printing technology and its forming principle at present. The advantage of metallic three-dimensional printing technology compared with the traditional manufactural technology is analysed. The research progress of three-dimensional printing technology in investment casting fields to manufacture gas turbine blades is introduced. The result shows that the three-dimensional printing technology has broad application prospects in the fields of rapid manufacture of blades for gas turbine.
Key words：gas turbine blades；3D printing technology；rapid manufacture and repairment；investment casting
