【Abstract】 By carefully and deeply analyzing and studying the solidification process of photopolymer resin and based on the vast experiments a mathematical model was developed for the calculation of reain shrinkage,and some conclusions were presented about how to reduce the ellects of resin shrinkage on the parts accuracy, which effectively solved the effects of the shrinkage on parts accuracy. In addition ,some requirements for the properties of resin used in the properties of laser rapid-prototyping were mentioned.更多还原
