Three dimensional (3D) printing technology of historistic development status was briefly introduced. Through the analysis and discussion of the powder feeder nowadays 3D printing technology of research and development at home and abroad, between domestic and international development known, there was still a gap. And also it was highlighted the current 3D printing powder feeder technology that there was low utilization rate of the powder, the powder feeding uneven, materials restrictions and other issues, and put forward possible solutions to the problem. On this basis, on the future of 3D printing technology of development trends have been summarized.
