Method for photocuring 3D printing of mother-of-pearl ceramic with random geometric mosaic interface
The invention discloses a method for photocuring 3D printing of mother-of-pearl ceramic with a random geometric mosaic interface, which comprises the following steps: 1) taking micron-sized flaky ceramic powder and micron-sized nearly spherical ceramic powder with high radius-thickness ratio as fillers of photocuring ceramic slurry, and selecting composite photosensitive resin as a photosensitive component of the ceramic slurry; 2) generating random geometric points, and connecting the points according to a random geometric rule to form a graph of a random geometric microgroove; manufacturing a polydimethylsiloxane film with a random geometric structure microgroove by adopting an engraving method according to the generated pattern; 3) selectively curing the ceramic slurry layer by layer on the polydimethylsiloxane film with the random geometric structure microgroove by using a photocuring printer, and printing a ceramic biscuit; and 4) preparing the mother-of-pearl structural ceramic with a second phase by adopting a degreasing-pre-sintering-dipping method. The method solves the problems that in the prior art, photocuring printing of the mother-of-pearl ceramic is difficult, and a printing interface does not have microstructure enhancement.
