The SLA/DLP 3d forming technology uses liquid light-cured resin, and the liquid light-cured resin is cured by radiation under light energy with specific wavelength, and becomes a solid cross-linked structure, and the material essentially belongs to thermosetting plastic materials, has higher cross-linking density than the traditional thermosetting cross-linked structure materials, has hard and brittle natural defects, poor fatigue resistance and poor ageing resistance, and cannot be applied to terminal products. The traditional dental prosthesis material is prepared by adding 70-90 wt% of ceramic reinforced material into photosensitive resin, and has the properties of toughness, wear resistance and the like. However, the dental photosensitive resin has a high viscosity and is difficult to use for 3D printing.

In order to achieve the purpose, the invention provides an oxide ceramic reinforced light-cured material for manufacturing a three-dimensional object, which comprises the following raw materials in parts by mass: 100 parts of photocuring organic matter, 20-400 parts of accelerant modified oxide ceramic powder and 0.12-30 parts of additive; the light-cured organic matter comprises a light-cured oligomer and a reactive diluent, and the mass ratio of the light-cured oligomer to the reactive diluent is 20-90: 10-80; the accelerant comprises a thixotropic accelerant and a strength accelerant, wherein the mass ratio of the thixotropic accelerant to the strength accelerant to the oxide ceramic powder is 0.5-10: 100; the additive comprises a photoinitiator, a light absorption agent and an antioxidant, wherein the mass ratio of the photoinitiator to the light absorption agent to the antioxidant to the photocuring organic matter is 0.1-10: 0.01-10: 100.

The invention has the following beneficial technical effects:
it is known to those skilled in the art that it is not difficult to add a large amount of inorganic oxide ceramic powder to the photosensitive resin, but in general, a large amount of inorganic inert powder is added because of poor dispersibility, which not only greatly deteriorates the viscosity uniformity of the photosensitive resin, but also causes poor thixotropy, which is not conducive to processing, but also greatly reduces the strength of the photosensitive resin after curing. According to the invention, the oxide ceramic powder is modified by a unique process through a functional thixotropic accelerant and a strength accelerant creatively, so that the liquid photosensitive resin still has good thixotropy-shear thinning after a large amount of modified oxide ceramic powder is added, the force applied to the photocuring material when the 3D printing platform falls is used for promoting the viscosity of the material to be reduced, and the 3D printing process can be smoothly carried out; meanwhile, the strength promoter and the thixotropic promoter can react to a certain degree, and oxide ceramic powder is attached and wrapped in sequence, so that a certain active functional group is endowed to the surface of the inorganic ceramic oxide powder, and the inorganic ceramic oxide powder can participate in the reaction during the curing of the photosensitive resin, thereby greatly improving the mechanical strength of the product.
