Lithography-based Ceramic Manufacturing as tool for the full digital workflow for the production of dental applications

A presentation by Sandra Balnik, Lithoz GmbH.

Lithography-based Ceramic Manufacturing (LCM), a 3D printingtechnologyfor ceramic materials, offers new possibilities for the manufacturing of dental medical devices. LCM usesceramic suspensions, which consist of ceramic particles dispersed in photocurable binder matrix, in a layer-by-layer process by using visible light.

After debinding and sintering pure ceramic parts are yielded with same properties as in conventional manufacturing techniques. Beside freedom of design other benefits of LCM compared to conventional shapingmethods are very efficient material usage, dimensional accuracyand the capability to generate very delicate features down to 100 μm. LCM allows a wide variety of ceramic materials to be shaped in order to produce among others dental restorations, dental implants and bone replacement implants.

For that purpose 3Y, 4Y and 5Y Zirconia,alumina, silicon nitride and lithium disilicate are the most used materials for restoration and permanent implants. Hydroxy apatite and tricalcium phosphate are frequently used for resorbable bone replacements and bone augmentation.

The main focus of this talk will be on LCM 3D printing of dental applications as well multi material 3D printingof different ceramic materials with the new CeraFab Multi 2M30 3D printer.The CeraFab System printers allow serial production of medical devices as well as patient-specific products based on STL files which come from CAD design, scanning or other medical imaging techniques. Last but not least, during this talk you will get a brief insight into the content of the Inkplant project.

About Lithoz GmbH
When it comes to people’s health, it is extremely important to have strong and competent partners. Lithoz possesses expert knowledge in this industry, and has a wide spectrum of products and services available which are specially suited to the manufacture of innovative and patient-specific products for medical applications. We offer customized solutions to doctors, researchers and manufacturers of medical devices throughout the entire process chain of the additive manufacturing of ceramics.

In contrast to materials already established in the medical field, such as metals or polymers, bioinert or bioresorbable ceramics possess properties which facilitate a multitude of new applications in the medicinal sector. Using the tool-free Lithography-based Ceramic Manufacturing (LCM) technology, it is possible to manufacture highly complex lattice structures, undercuts and channels with dimensions of up to 100 µm. The limitations of conventional manufacturing technology (such as milling or injection molding) are largely eliminated, and the development and production of components for medical devices, surgical instruments, dental prostheses and patient-specific implants is possible. The result is a batch-orientated process for producing individualized components, with the additional possibility of series production.
