A novel cationic photosensitive resin (3DSLR-01) for stereolithography 3D printing was prepared with 3,4-epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate (2021P), 1,4-cyclohexanedimethanol glycidyl ether (JX-026), diglycidyl 4,5-epoxycyclohexane-1,2-dicarboxylate (S-186), polycaprolactone polyol(Polyol-0305), novolac epoxy resin(F-51), bis(3-ethyl-3-oxetanylmethyl) ether (S-221) and a mixture of triarylsulfonium hexafluoroantimonate salts solution (UVI-6976). The properties of the photosensitive resin and its UV-cured films were investigated by some instruments and equipment. The experimental results show that the critical exposure ( E c ) of the photosensitive resin is 16.3 mJ/cm 2 , the penetration depth ( D p ) is 0.14 mm, and the optical property of the photosensitive resin is excellent. Rectangle plates were printed by using a stereolithography apparatus (HRPL-150A) with the photosensitive resin as the manufacturing material, and the shrinkage rates of the plates were less than 0.60%, which showed that the accuracy of the manufactured plates was very high.
