The continual need for new materials and their combinations that can tolerate different conditions by providing properties and functions at different positions led to the design of multi-material components. Significant developments in manufacturing technologies especially in additive manufacturing (AM) enable us nowadays to manufacture multi-materials that can improve functionality and performance by combining different material properties in a single component. Lithography-based Ceramic Manufacturing (LCM), a method developed by Lithoz GmbH as an enhancement of stereolithography and digital light processing (DLP) technology, offers layer-by-layer printing by curing a photosensitive formulation with a mask-exposure process using the concept of DLP in the required areas through selective light exposure to light. A newly developed 3D printer type allows the deposition of multi-materials by simultaneous processing of two photocurable feedstocks. Various methodologies have been introduced that enable multi-layered and functionally graded ceramic-ceramic multi-material combinations that have different compositions, microstructure, and porosity. This study investigates the performance of printing methodologies of ceramic-ceramic multi-materials in terms of printability, precision, and functionality.
