Forming ability and quality of fine ceramic structure fabricated by vat photopolymerization

Abstract

In recent years, ceramic additive manufacturing technology based on vat photopolymerization has been widely used in various fields. This technology has amazing structural design freedom and forming precision. However, the printed structure can't be regarded as a simple reproduction of the virtual model. In our work, by analyzing the characteristic edge structure caused by the uneven propagation of exposure energy in ceramic slurry, we explore the manufacturing limits of fine structure in ceramic vat photopolymerization and the reasons for the decline in fine structure printing quality. The ability of ceramic vat photopolymerization to construct fine structures was improved by personalized selection of exposure energy. This work plays an important role in studying and expanding the ability of ceramic vat photopolymerization to construct fine structures.
