Digital Light Processing Based 3D Printing of YAG∶Ce Transparent Ceramics
Rare-earth-doped transparent ceramics hold significant potential for applications in high-power lighting,solid-state laser gain media,high-energy radiation detection and imaging,and other fields.With the emergence of new design concepts and application technologies,there is a demand for the preparation of transparent ceramics with novel configurations or composite functions.However,traditional forming methods struggle to achieve the integrated forming of transparent ceramics with special structures and functions.This study focused on the DLP photocuring 3D printing technology for rare-earth doped transparent ceramics,systematically carrying out the component design of transparent ceramic slurry and the optimization of printing parameters.By optimizing the ceramic slurry components,YAG∶Ce transparent ceramics with a transmittance of about 72％in the visible light range were successfully fabricated.Moreover,by using low exposure energy with a smaller curing depth,the warping of ceramic samples was minimized,enabling precise control over the shape of YAG:Ce transparent ceramics.
