Beschreibung
Zusammenfassung:	The present invention provides a two-photon 3D printing photosensitive resin composition, and relates to the technical field of two-photon 3D printing, and the two-photon 3D printing photosensitive resin composition comprises the following components by weight: 5-20 parts of a hydroxyl group-containing light-cured resin prepolymer; 35 to 50 parts of a UV acrylate monomer; 33 to 67 parts of a long-chain hydrophilic crosslinking monomer; and 2-5 parts of a photoinitiator. According to the two-photon 3D printing photosensitive resin composition provided by the invention, through the synergistic effect of the light-cured resin prepolymer containing the hydroxyl group, the UV acrylate monomer and the long-chain hydrophilic crosslinking monomer, under the initiation of the photoinitiator, the two-photon 3D printing photosensitive resin composition can be rapidly cured, the flexibility of a printed product is improved while two-photon 3D printing forming is ensured, and the service life of the printed product is pro
