3Y-TZP strengthened ZrO2 ceramics were fabricated by using digital light processing (DLP) based additive manufacturing. The effects of 3Y-TZP concentration on the relative density, linear shrinkage, microstructure, and mechanical properties of the DLP-prepared ZrO2 ceramic were investigated in detailed. High precision ZrO2 ceramic parts with lattice structure with parts were successfully prepared by using DLP. The highest relative density and flexural strength were 96.40% and 306.53 +/- 6.03 MPa, respectively, when the 3Y-TZP concentration was 7.5 vol%. The strengthening mechanism was discussed in detailed.
