Abstract To evaluate the effects of inorganic micron, nano and micro-nano particles synergistic modification on the viscosity, curing shrinkage characteristics and mechanical properties of photosensitive resin, micro-nano SiC/ZnO modified photosensitive resins with different mass ratios were prepared by LCD light-curing 3D printing technology. The results show that: under the co-doping of nano-ZnO and micron SiC fillers, the viscosity of the resin gradually decreases as the mass ratio of SiC fillers increases, which can effectively improve the spreading ability in printing; at the same exposure energy, combined with Beer-Lambert model equation, it is found that compared with the nano-ZnO/resin system, the micro-nano SiC/ZnO/photosensitive resin has higher curing depth, which facilitates forming. When the mass ratio of micron-SiC to nano-ZnO is 0.5∶2, the curing shrinkage, shore hardness, tensile strength and elongation at break of the photosensitive reach the optimal effect, which are 0.39%, 96.2, 21.9 MPa and 4.89% respectively. In this work, micro-nano SiC/ZnO/resin system were prepared by LCD light-curing 3D prin-ting, which provides a certain reference for the forming of micro-nano synergistic modified photosensitive resin fabrications in the future.
