Digital light processing of 3Y-TZP strengthened ZrO2 ceramics

3Y-TZP strengthened ZrO 2 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 ZrO 2 ceramic were investigated in detailed. High precision ZrO 2 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.
