This invention discloses a digital light-processing 3D printing photocurable resin composition, its printing method, and its applications. The digital light-processing 3D printing photocurable resin composition includes a crosslinking agent, a monomer, a chain transfer agent, and a photoacid. By introducing a thioacetal compound as a chain transfer agent, this invention constructs a photoinitiated cationic degenerate chain transfer polymerization system under the action of a photoacid catalyst, achieving active / controllable regulation of the polymerization process. The photocurable resin composition provided by this invention has a simple composition, requires no complex synthetic reagents, and can fundamentally eliminate oxygen inhibition, achieving rapid and high-precision 3D printing with a maximum printing resolution of 57 μm.
