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 photo-sensitive resin density was 1 .1 7 g/cm3 ,its UV-cured density was 1 .2 1 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 elonga-tion at break and 47 ℃ of glass transistion temperature.With 3DPSL-1 type photosensitive resin as the process-ing material,the part of a flexible pliers was fabricated by selecting the processing parameters of the stereo-lithography apparatus (HRPL-I),and the quality of the fabricated part was good.The preparation of the photo-sensitive resin will promote the further development of the domestic 3D printing stereolithography technique to play a positive role.
