Large-size photocuring 3D printing ceramic and preparation method thereof
The invention discloses a large-size photocuring 3D printing ceramic and a preparation method thereof, and relates to a 3D printing ceramic and a preparation method thereof. The invention aims to solve the problems of low mechanical property and thermal stability caused by incomplete curing of a large-size green body and deformation and cracking caused by internal and external temperature difference in the existing three-dimensional photocuring technology. The large-size photocuring 3D printing ceramic is prepared from ceramic powder, reinforced phase powder, a photosensitive resin monomer, an epoxy-anhydride prepolymer, a heat conduction agent, a dispersing agent, a thermal initiator and a photoinitiator. The method comprises the following steps: 1, preparing an epoxy-anhydride prepolymer; 2, preparing ceramic photosensitive slurry; 3, printing a large-size model; and 4, performing post-treatment on the green body. The invention is used for the large-size photocuring 3D printing ceramic and the preparation thereof.
