English abstract:
Lithography-based Additive Manufacturing Technology is a layered manufacturing approach where liquid photopolymerizable resins are solidified with ultraviolet, visible or infrared light. Using a system based on digital mirror devices, photopolymers can be exposed selectively in order to build parts with defined geometries. Various power-filled formulations were developed for fabricating customized ceramic parts made of alumina, zirconia, tricalcium phosphate or bioactive glasses, respectively. Target application include high-performance engineering ceramics and ceramics for digital dentistry. For alumina > 99 % of theoretical density was achieved, for zirconia >99.8%. The biaxial bending strength of alumina parts exceeds 500 MPa.
