One of the most important factors in determining accuracy in stereolithography is the deformation phenomenon caused by the volume shrinkage of resins that accompanies photopolymerization. The objective of the work described in this paper is to perform finite element analysis of this deformation of parts built by stereolithography. We propose an element division method for the analysis of shape and dynamic resin material models based on the properties of resin after photopolymerization. Utilizing these, we will demonstrate simulation parts building, and demonstrate the usefulness of them and influence of their parameters on the deformation of parts.
