Fabricating and testing of three dimensional model with photohardening polymer

This paper described the fabrication method of the plastic model by using the fast liquid photohardening polymer. The physical,chemical,and photo-sensitive performance of the photopolymerare presented in this paper. When a model was rotating on a circular index table,the parameters of thecircular flat surface were tested and controlled with a computer system. The roudness and the variationcurves of the flat surface were tested.
