In this study, hybrid light curing compositions suitable for the production of flexographic plate through 3D printing were investigated. Several resins such as V400, E44, and TTA26 were selected as the pre-polymer to prepare the free radical-cationic hybrid light curing materials. Through the fully study of viscosity, surface tension, flexibility, curing speed and the volume shrinkage and other properties of the curing compositions, the formula of the curing composition was optimized. The optimized hybrid light curing composition might be applied to the development of flexographic plate based on 3D printing technology.
