Y-TZP, Ce-TZP and as-synthesized Ce-TZP/Al2O3 materials in the development of high loading rate digital light processing formulations

Y-TZP, Ce-TZP and Ce-TZP/Al2O3 materials are widely investigated in dentistry. Digital Light Processing (DLP) is considered as a breakthrough technology for the dental field to fine print Y-TZP green parts. High loading photocurable formulations (>45 vol%) with commercial powders Ce-TZP/30 vol% Al2O3 as-synthesized powder suitable DLP printing were achieved this study. A low specific surface area (5–13 m2/g) of particles without any pores 1 wt% 2 steric dispersant required obtain high formulations. The composites provide these properties by increasing calcination temperature from 800 °C 1200 °C. as-prepared ceramic based on same resin exhibit curing behavior process (thickness > 50 ?m few seconds conversion rate) comparison ceria ceramic. strongly UV absorbing material formulation developed 80% cured thickness 75 0.5 s.
