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打印技術(shù)是一系列快速原型成型技術(shù)的統(tǒng)稱(chēng)，其基本原理都是疊層制造，由快速原型機(jī)在X-Y平面內(nèi)通過(guò)掃描形式形成工件的截面形狀，而在Z坐標(biāo)間斷地作層面厚度的位移， 終形成三維制件。目前市場(chǎng)上的快速成型技術(shù)分為3DP技術(shù)、FDM熔融層積成型技術(shù)、SLA立體平版印刷技術(shù)、SLS選區(qū)激光燒結(jié)、DLP激光成型技術(shù)和UV紫外線(xiàn)成型技術(shù)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.
