Lithoz GmbH, based in Vienna, specializes in the development and production of ceramic materials and additive manufacturing systems (3D printing) for the simple and cost-effective production of high- performance ceramic prototypes, small scale series and complex parts.


Lithoz offers a process for the additive manufacturing of high-performance ceramics which is called Lithography-based Ceramic Manufacturing (LCM)-Technology. The LCM-Technology allows the production of high-performance ceramic parts with the same material properties as conventionally formed parts. The development of the LCM-Technology started in 2006 at the TU Vienna by the founders of Lithoz. In 2011 the Lithoz GmbH was founded as a spin-off of the TU Vienna.

The LCM-Technology is a slurry-based process, where ceramic powder is homogenously dispersed in a photocurable monomer system and selectively polymerized through mask exposure to initially give the so-called green part. These green parts are basically composites of ceramic particles within a photopolymer matrix, which acts as a binder for the ceramic particles. During the thermal post-treatment the organic matrix is removed via pyrolysis and the particles are densified during sintering to give the dense ceramic body. These two process steps are typically applied as well in the conventional ceramic forming technologies.

Generally speaking, the LCM technology is suited to process all powder-like and sinterable powders. This has led to processing a wide spectrum of customer-specific materials with the LCM approach over the last years.
