Cure Shrinkage

This paper reports on a combined analytical and experimental investigation undertaken for the determination of polymerisation shrinkage strains resulted in photopolymer resin plates during the laser solidification process. A resin layer is laser cured on an identical layer of the same material that already has been cured and post cured under ultraviolet (UV) exposure. The assembled laminate is then UV cured, and the resulting warpage is recorded by means of the shadow moirtι method. The resulting warpage, consisting of elliptical equal deflection contours, is related to the polymerisation effective chemical shrinkage strain using the elastic lamination theory.
