3D printing is a digital material manufacturing technology which makes three dimensional objects by adding material layer by layer. It combines many contemporary high technology and will have an important effect on the manufacturing production mode and the way of human life in the future. The development of 3D printer＇s key technology was introduced and the way 3D printer was based on fused deposition modeling. The key technology were summarized from three parts：the establishment of data model, rapid prototyping technology and post-processing technology. The effect of key technology on the quality of parts was introduced.
