Application of low-viscosity light-cured resin in 3D (three-dimensional) printing materials

The invention relates application of low-viscosity light-cured resin in 3D (three-dimensional) printing materials. The low-viscosity light-cured resin is (branched) polyether acrylate or heterocyclic amine modified (branched) polyether acrylate. A 3D printing material prepared from the low-viscosity...

Zusammenfassung:	The invention relates application of low-viscosity light-cured resin in 3D (three-dimensional) printing materials. The low-viscosity light-cured resin is (branched) polyether acrylate or heterocyclic amine modified (branched) polyether acrylate. A 3D printing material prepared from the low-viscosity light-cured resin is of low viscosity and high curing speed, is low in curing shrinkage, low in yellowing property, moderate in rigidity and flexibility, high in forming speed and high in product dimensional precision, is free of curing incompleteness, edge warping and the like, and is very suitable for being applied to 3D printing materials based on the SLA (stereolithography) or 3DP (three-dimensional printing) technology.
