Water-based ceramic three-dimensional laminate material and method for using the same to manufacture ceramic objects

A method of manufacturing a ceramic object using a water-based ceramic three-dimensional laminate material, comprising:

• a step (Sa) of preparing a plurality of projected slice graphics and a slurry, wherein the projected slice graphics are generated by slicing a three-dimensional image along a specific direction with a specific thickness;
• the slurry is prepared by mixing material powder, photo-curable resin, solvent and additive;
• the photo-curable resin comprising at least one of a water-soluble resin and a water-dispersible resin;
• the solvent is water or a mixed solvent comprising water and alcohols, and the additive includes at least one of a dispersing agent, a binder, and a plasticizer;
• a step (Sb) of uniformly laying the slurry on a substrate to form a sacrificial layer;
• a step (Sc) of uniformly laying the slurry on the sacrificial layer to form a reaction layer;
• a step (Sd) of irradiating a light beam to the reaction layer by using one of the plurality of projected slice graphics, wherein the slurry in the reaction layer irradiated by the light beam is cured and solidified, wherein the light beam emitted from a light source is a visible light or an ultraviolet light, and the light source is provided above the substrate;
• a step (Se) of repeating the steps (Sc) and (Sd) until a ceramic body is formed;
• a step (Sf) of cleaning the ceramic body;
• and
• a step (Sg) of sintering the ceramic body at a high temperature to form a ceramic object, characterized in that:
• the material powder for preparing the slurry comprises at least one of aluminum oxide powder, zirconium oxide powder, and glass ceramic powder and
• the substrate is composed of a material or structure having a water absorption rate of 5% or more.
