WIPO Patent Application WO/2021/218097
Kind Code:
A1
Abstract:
The present invention relates to a dual-curing phase separation type continuous 3D printing high-precision photosensitive resin composition, comprising an acrylate with a crosslinkable double bond, a polyurethane prepolymer, a chain extender and a photoinitiator, wherein the polyurethane prepolymer is produced by means of a heating reaction of an isocyanate and a polyether polyol with a molecular weight of greater than or equal to 4000 under the action of a catalyst. The photosensitive resin composition of the present invention is used for preparing high-precision parts during continuous 3D printing.
