Hydroceram

Picture of the kick-off meeting in Shanghai (Sep 2015) with partners from Shanghai University, TU Wien and Lithoz.

Hydroceram aims at establishing water-based photopolymers (hydrogels) with ceramic nano-particles as fillers for lithography-based AMT. Two application fields will be explored within this project: (1) Biocompatible and biodegradable hydrogels filled with calcium phosphates as potential implant materials and (2) environmentally friendly, ceramic filled photocurable hydrogels  for the manufacturing of zirconia parts.

The project requires developments in two fields of research: Synthesis and characterization (1) of innovative photocurable monomers based on hydrophilic methacrylates and vinyl esters which are sufficiently reactive for being processed in lithography-based additive manufacturing equipment (e.g. stereolithography). (2) Development of new nano-particulate ceramic particles will allow the formulation of ceramic filled bio-hydrogels as well as zirconia-filled photopolymers for the manufacturing of dense ceramic parts. The targeted nano-particles offer two benefits over traditionally used materials: The required sintering temperature can be lowered significantly, leading to a finer ceramic microstructure and better mechanical properties. Additionally, problems with settlement of particles inside the photocurable formulation can be reduced.

The project is funded by the FFG and involves partners from TU Wien (coordinator Prof. Stampfl), Shanghai University (Prof. Shuai YUAN) and Lithoz GmbH.
