Abstract: By combining finite element simulation and experimental verification, the influence of the thickness of the curing layer （0.01−0.11 mm）, the number of curing layers （10−100 layers）, the shape of the model cross-section and the sudden increase in area of the curing layer on the deformation degree and dimensional accuracy of the cylinder model section during liquid crystal display (LCD) photo-curing printing was studied. The results show that the influence of the curing layer thickness on the section deformation of the model could almost be ignored. As the number of curing layers increased in printing, the rate of deformation in the radial and forming directions and the increase in dimensional shrinkage of the model gradually slowed down. In the later stage of printing, the degree of deformation was intensified, and the dimensional shrinkage significantly increased. The more curing layer total number, the weaker the degree of deformation and the smaller the dimensional shrinkage under the same number of layers in the middle. For hollow cylinder models with the same outer radium but different diameters of middle hollow and eccentric distances, the larger the diameter of the middle hollow or the greater the eccentric distance, the greater the radial shrinkage of the model, and the simulated variation trend of the deformation was consistent with the experimental results. When the area of the new layers suddenly increased and there was no support or printing compensation during the printing, the area with the sudden increase in area underwent relatively severe deformation in the radial and forming directions; as the degree of area mutation increased, the degree of deformation also increased.
