A comparative study on 3D printed silicone-epoxy/acrylate hybrid polymers via pure photopolymerization and dual-curing mechanisms

A type of silicone-epoxy resin has been synthesized and compounded with acrylates to obtain hybrid inks for stereolithography 3D printing. Two approaches of printing have been developed: one approach is pure photopolymerization through the addition of free radical and cationic photoinitiators to the hybrid resin; the other approach untilizes a photo-thermal dual-curing system with free radical photoinitiator for acrylates and thermal curing...
