Abstract
In order to reduce the time to market of new or customized porcelain products or artworks, rapid prototyping using layer-wise slurry deposition (LSD) was studied in the present research. The properties such as phase composition, microstructure, shrinkage, density, and mechanical strength, of laser sintered (LS) and biscuit fired (BF) samples before and after post sintering in a furnace were studied and compared with each other. The laser sintered sample was comparable with the biscuit fired one in porosity, but just had a half mechanical strength of the latter. The feasibility of rapid prototyping of porcelain products was validated by the successful fabrication of two models (lavatory and double-heart) which showed that the relatively low mechanical strength of laser sintered sample was still high enough for the following handling processes.
