The motion precision of the translation stage in high-resolution Stereolithography System is the basic for RP system to fabricate object with high dimension accuracy. The motion precision of the translation stage in high-resolution Stereolithography System was investigated and estimated, and the experiments results indicate that the unidirectional accuracy of positioning in Z direction is 6.4µm, and the unidirectional repeatability of positioning of the translation stage in Z direction is 6.4µm. The motion precision of the translation stage can satisfy the requirements of high-resolution SL system. The phenomena that the unidirectional positioning system error and the unidirectional repeatability positioning accuracy have distinct difference was researched, and it is fund that different load status of the translation stage is the main reason during the translation stage moving up and down.
