When we choose to use rapid prototyping, we need to pay more attention to its quality in all aspects, and we need to have a certain degree of attention to these quality, which is to ensure that we can get a better use effect when we use them, which is a great guarantee for its service life nature.

　　3D打印技术是一系列快速原型成型技术的统称，其基本原理都是叠层制造，由快速原型机在X-Y平面内通过扫描形式形成工件的截面形状，而在Z坐标间断地作层面厚度的位移， 终形成三维制件。目前市场上的快速成型技术分为3DP技术、FDM熔融层积成型技术、SLA立体平版印刷技术、SLS选区激光烧结、DLP激光成型技术和UV紫外线成型技术等。

　　3D printing technology is a general term for a series of rapid prototyping technologies. Its basic principle is laminated manufacturing. The cross-section shape of the workpiece is formed by the rapid prototyping machine through scanning in the X-Y plane, and the displacement of the layer thickness is made intermittently in the Z coordinate to finally form a 3D workpiece. At present, the rapid prototyping technology in the market is divided into 3DP technology, FDM melt lamination technology, SLA stereo lithography technology, SLS selective laser sintering, DLP laser molding technology and UV UV molding technology.
