FOR THE ADDITIVE MANUFACTURING OF HIGH PERFORMANCE CERAMICS
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 term additive manufacturing describes processes with which three dimensional objects are created by stacking individual layers. In the last few years, additive manufacturing, often referred to as 3D-printing, has emerged as an effective tool-free method for producing objects of diverse complexity straight from CAD data. The root of its success are the significant advantages that additive manufacturing technology offers industry and research.
- cost-effective and fast production method for prototypes, single parts and small-scale series
- customization and mass customization of products
- improved products through function-oriented design
- shortening of TTM and increased pace of innovation within the company
- more flexible reaction to market needs
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.
