  • Patent number: 11771534
    Abstract: The present invention relates to an apparatus and method for three-dimensionally laminating a ceramic denture in a color-and-transmittance variable manner. A base slurry and a light transmissive slurry are mixed at a ratio regulated by a main controller according to a slurry ratio parameter datum, and then a slurry mixture is laid on a substrate by a laying module to form a slurry layer; next, the slurry layer is photocured by a photocuring module according to a laminated graphic under control of the main controller; in such a manner, the slurry layers are laminated and cured one by one so that a denture green body is formed; finally, the denture green body is sintered at a high temperature to form a ceramic denture. The present invention allows each slurry layer to exhibit different color and transmittance, resulting in quite natural gradation of color and gradation of transmittance.

  • Patent number: 11453617
    Abstract: The invention relates to a water-based ceramic three-dimensional laminate material and a method for using the same material to manufacture the ceramic objects, comprising: a step Sa of preparing a plurality of projected slice graphics and a slurry, wherein the projected slice graphics are formed by slicing a three-dimensional image along a specific direction with a specific thickness, the slurry is prepared by mixing the material powder, the photo-curing resin, the solvent and the additive; a step Sb of uniformly laying the slurry on the substrate to form a sacrificial layer; and a step Sc of uniformly laying the slurry on the slurry to form a reaction layer on the sacrificial layer; a step Sd of irradiating the reaction layer with a light beam according to one of the plurality of projected slice graphics, and the slurry is cured after being irradiated; a step Se of repeating steps Sc and Sd until a ceramic body is formed; a step Sf of washing the ceramic body with water or an organic solvent; and a step Sg o
