Continuous lamination manufacturing method for preparing ceramic product and ceramic product

The present disclosure provides a method of making a ceramic article. The method comprises (a) obtaining a photopolymerizable slurry or sol, the photopolymerizable slurry or sol comprising a plurality of ceramic particles distributed in the photopolymerizable slurry or sol; and (b) selectively polymerizing the photopolymerizable slurry or sol to form a gelled article using actinic radiation and constructing continuous movement of a substrate through the photopolymerizable slurry or sol. The method further includes (c) extracting a solvent from the gelled article to form an aerogel article or a xerogel article; (d) heat treating the aerogel article or the xerogel article to form a porous ceramic article; and (e) sintering the porous ceramic article to form a sintered ceramic article. The sintered ceramic article exhibits a specific density. In addition, the present disclosure provides laminated manufactured ceramic articles exhibiting a particular density, opacity, or both. Preferably, all cross-sectional port
