Provided is a preparation method of a porous
ceramic material rapidly formed based on photocuring. The preparation method comprises the steps that firstly, a photo-cured resin
prepolymer, an active
diluent and a surface modifier are evenly mixed to obtain a premixed solution,
ceramic powder and a pore-forming agent are mixed to obtain porous
ceramic powder, then the porous ceramic
powder is mixed in the premixed solution to obtain primary
slurry, and then a
photoinitiator is added to prepare a photocured porous ceramic
slurry; the ceramic
slurry is put in a photocuring forming device to prepare a photocuring forming blank; finally the blank is degreased and sintered to obtain the porous ceramic material. By designing and optimizing the components and proportion of the photocured porous ceramic slurry and using a photocuring 3D printing device, the limitations of traditional mold
processing to shapes are overcome. The micropores formed by adopting the pore-forming agent and macropores for 3D printing are combined, and the high-
porosity foam ceramic material can be prepared. In addition, the macropores are controllable in shape and distribution, and gradient porous ceramic material can be prepared.
