In this research, sub-region curing and mask DPI modification are used to improve the accuracy of MPSL. Because the curing shrinkage at the discrete region does not cause the shrinkage of the entire resin surface, the accuracy of the RP work piece under sub-regional MPSL can be improved effectively. For the optical system error, the accuracy can be improved through the DPI (Dot per Inch) modification. The research results show that accuracy of work piece less than 12mm can be improved through DPI (Dot per Inch) modification. For the work piece above 16mm, the main method which improves the accuracy can adapt sub-region curing procedure. The combination methods of sub-regional exposure and exposure mask DPI modification can significantly improve the dimensional accuracy of parts, and the overall size of the error of parts can be controlled less than 1%.
