Theoretical Modeling and Experimental Characterization of Stress Development in Parts Manufactured Through Large Area Maskless Photopolymerization

Abstract

This paper aims at investigating the evolution of stresses in parts manufactured through large area maskless photopolymerization (LAMP). A theoretical model was established to understand the curing process for LAMP and a finite element analysis was performed to model the dynamic evolution of stresses during the layer-by-layer fabrication process using Abaqus software. This model serves to suggest strategies for reducing stresses, part warpage, and crack development in parts made through LAMP.
