Gradient functional ceramic material based on photocuring 3D printing and additive manufacturing method thereof
The invention discloses a gradient functional ceramic material based on photocuring 3D printing and an additive manufacturing method of the gradient functional ceramic material. The method comprises the following steps of: constructing a series of equidistant parallel cylinders of which the diameters are gradually and equivalently changed along the common perpendicular direction of parallel straight lines; constructing transversely staggered connecting structures between the parallel cylinders to obtain gradient structures; constructing an equidistant multi-layer gradient structure, and constructing a transversely staggered connecting structure between the parallel cylinders of each layer to form a main body of the gradient structure; carrying out photo-curing 3D printing molding to obtaina gradient structure resin mold; preparing matrix ceramic slurry, carrying out ball milling, carrying out gel film injection, and carrying out pre-freezing; carrying out freeze-drying and degreasingand sintering to obtain a porous ceramic prefabricated body; and carrying out an impregnation cracking process and a siliconizing process on the porous ceramic prefabricated body, filling structural holes to realize integral densification so as to obtain the gradient functional ceramic material. The additive manufacturing of the gradient functional ceramic material is realized.
