Thermal shock resistance is critical to ensure the service safety of ceramic hot-end components. The thermal shock performance of stereolithog. additive-manufactured ceramics has not yet been studied. In this study, a series of thermal shock experiments with various temperature differences was conducted on stereolithog. additive-manufactured Al2O3 ceramics. The surface cracks were analyzed based on photographs captured before and after the thermal shock experiments Three-point bending tests with in situ X-ray digital radiog. were conducted to determine the thermal shock resistance. Crack initiation, propagation, and coalescence were observed under flexural loads. The critical temperature difference of the stereolithog. additive-manufactured Al2O3 ceramics was determined to be 267.22 °C. The crack length increased and residual strength decreased with increasing temperature differences. The layered structure of the stereolithog. additive-manufactured ceramics slowed crack propagation. We expect that this study will serve as a reference for the performance of stereolithog. additive-manufactured Al2O3 ceramics in extreme environments.
