Abstract

In the current study, materials and systems for the fabrication of customized bioceramic parts by using lithography-based additive manufacturing techniques (AMT) are presented. By using this modified system based on digital mirror devices, which relies on a selectively polymerization of a photosensitive ceramic filled resin, structures with a resolution of 40 um can be generated. By modifying the working DLP-system (Digital Light Processing) a resolution of 25 um could be reached. The building volume ranges from 77 × 43 × 115 mm to 115 × 65 × 160 mm, depending on the used optics. Photocurable ceramic suspensions with a high solid loading of ceramic powders can be processed. Depending on the ceramic powder and the field of application, delicate bioceramic parts with coordinated properties made of alumina, tricalcium phosphate (TCP) or bioactive glass were fabricated and characterized.
