【Abstract】 Photo-cured three dimension(3D) printing technology has been widely used for biomedical application such as construction of tissue and organ. Hydrogel is the most commonly used 3D bioprinting material, and its mechanical property is one of the important factors affecting the quality of 3D printed biological products. This article summarizes the methods to improve the mechanical properties of photo-cured 3D printing hydrogels, including hydrogel network structures, preparation process conditions and 3D printing architectures. Furthermore, the challenges of mechanical properties of photo-cured 3D printing hydrogels are discussed. This review provides a reference for improving the mechanical properties of photo-cured 3D printed hydrogels.更多还原
