The application of Additive Manufacturing (AM) processes for ceramics offer high innovation potentials with regard to process technology, design and possibility to generate new types of composite materials and gradient materials. Based on a CAD record the respective ceramic part is generated layer by layer without using a mold. Thus, the production of ceramic components with complex geometry, for example with freeform areas, undercuts und hollow structures is possible. Within the framework of R&D it has already been proven that all current AM processes can be adapted to ceramics offering promising application potential for the production of complex ceramic components in the future.
