Effects of solid loading on stereolithographic additive manufactured ZrO2 ceramic: A quantitative defect study by X-ray computed tomography

Abstract In this study, the effects of solid loading on the defects and mechanical performance of stereolithographic additive manufactured ZrO2 ceramic were studied by X-ray computed tomography (X-CT). ZrO2 ceramics were fabricated by stereolithographic additive manufacturing from suspensions with different solid loading. The geometrical features and distribution of the defects within the ceramic were quantitatively characterized, classified, and analyzed, the formation mechanism were discussed. The correlations between the defects and mechanical properties were also investigated, and the effects of solid loading on the performance of ZrO2 ceramic were revealed. The authors want to give a method, X-CT, for the defect characterization among stereolithographic additive manufactured ceramic.
