| Abstract Scope |
Transparent ceramics have been fabricated by using nozzle extrusion 3D printing methods and lithography-based digital projection. The ceramic green bodies were printed into complex geometries by using different viscous aqueous slurries. Transparent alumina ceramics were fabricated using an extrusion-based 3D printer and post-processing steps including debinding, vacuum sintering, and polishing. Scalable, massive fabrication of complex three-dimensional (3D) structured highly transparent Nd: YAG (Y3Al5O12) ceramics was achieved by a lithography-based (photopolymerization) digital light processing or digital light projection (DLP) 3D printing method. The work demonstrated transparent ceramics can be prepared using a simplified process without the traditional mold and cold isostatic pressing procedure. It can serve as a potential method of making customized transparent ceramic components and it is also useful for fabricating ceramics structures with relatively full densification. |
