As an emerging rapid manufacturing technology, 3D printing has received great attention from many fields such as biomedicine, aerospace and intelligent devices due to its unique manufacturing advantages. 3D printing is based on the principle of layer-by-layer stacking of materials: using a computer-designed three-dimensional model as a blueprint, and then performing heating and melting, laser sintering or light curing to stack materials layer-by-layer to form the desired solid parts. Among them, photo-curing 3D printing is one of the most important 3D printing methods, demonstrating advantages in high resolution and high efficiency. Herein, we summarize the latest research progress of photo-curing 3D printing polymer materials. The bionic materials, hydrogel materials, porous materials, polymer-derived ceramic materials for 3D printing are summarized, while functional polymers with electrically/thermally conductivity, shape memory, self-healing and recycling ability are also generalized. Finally, the future perspective for photo-curing 3D printing polymer materials is discussed.
