摘要：

The paper was reported that the method was prepared with 3DPSL-1 type photosensitive resin for 3D printing stereolithography technique, and the properties of the photosensitive resin were investigated. The main parameters of 3DPSL-1 type photosensitive resin are as follows: the penetration depth (Dp) was 0.14 mm, the critical exposure (Ec) was 14.1 mJ/cm2, and the viscosity at 30℃ was 359 mPa·s. At 25℃, 3DPSL-1 photosensitive resin density was 1.17 g/cm3, its UV-cured density was 1.21 g/cm3, and the cured volume shrinkage rate was 3.31%. The mechanical property and thermal property of the UV-cured 3DPSL-1 type photosensitive resin were determined, giving 21.0 MPa of tensile strength, 1 108.2 MPa of tensile modulus, 10.6% of elongation at break and 47℃ of glass transistion temperature. With 3DPSL-1 type photosensitive resin as the processing material, the part of a flexible pliers was fabricated by selecting the processing parameters of the stereolithography apparatus (HRPL-I), and the quality of the fabricated part was good. The preparation of the photosensitive resin will promote the further development of the domestic 3D printing stereolithography technique to play a positive role. ©, 2014, Journal of Functional Materials.
