Abstract：Stereolithographic 3D printing technology has characteristics of fast forming speed and high precision, which allow it to accurately control the size, shape and strength of 3D printing soft tissue scaffolds, complete the high matching customization, and effectively solve the huge gap of the soft tissue replacement. At present, the application scope of this technology depends on the properties of photosensitive materials. Firstly, it is necessary to have appropriate viscosities, curing times and curing shrinkage rates for accurately controlling the soft tissue scaffolds by stereolithographic 3D printing. Secondly, printing tissues need to meet the mechanical properties (such as strength, hardness, toughness) and good biocompatibility (such as promoting cell adhesion, proliferation and differentiation), which were directly affected by degradation, porosity and vascularization. This review discussed the performance requirements and the improvement methods and the trends of photosensitive materials, aiming to provide guidance and insights to the development of photosensitive printing materials for soft tissue engineering.
