Interlayer crack is a significant obstacle to the wide-scale implementation of light-cured additive manufacturing in industrial applications. The formation mechanism of crack defects during the forming and debinding stages of the process is investigated and their effects on the properties of light-cured ZrO2 ceramics are analyzed. Furthermore， the study compares and analyzes the influence of exposure time and debinding rate on the distribution of cracks in ZrO2 ceramics. The research analyzes and compares the influence of exposure time and debinding rate on the distribution of cracks in ZrO2 ceramics. The results indicate that it is easier to obtain defect-free ceramic green bodies when the slice thickness matches the exposure layer thickness. Moreover， the study observes that the green body exhibits the least number of surface cracks when the debinding rate is set at 0.1 ℃/min. Consequently， the research achieves the successful production of ceramic parts with a density of 99% and a flexural strength of 450 MPa.These findings establish a solid scientific foundation and provide valuable technical guidance for the manufacturing and application of defect-free ZrO2 ceramics using light-cured additive manufacturing.
