Ceramic additive manufacturing (AM) is a method for manufacturing three-dimensional ceramic parts. There are several sub-technologies available for ceramic 3D printing that are classified according to the raw material’s nature (slurry, powder or solid). Lithography-based ceramic manufacturing (LCM) is an additive manufacturing (AM) method that works according to the principle of digital light processing (DLP), where a photosensitive slurry is selectively cured at desired areas by exposing it to UV light. The LCM method has high potential for industries that require high-precision ceramic parts. The advantages of the LCM method include the ability to produce complex geometries in a one process step without the need for machining or assembly processes, if required, and weight saving by optimizing the internal shape. However, there are still challenges in producing 3D ceramic parts by the LCM method that are related to the ability to achieve dimensional accuracy and the ability to produce specific shapes like holes or tubes. These challenges result from the combination of printing resolution limitation and the post-processing steps (debinding and sintering).

In this talk, I will focus on the advantages and challenges of the LCM method by demonstrating parts based on alumina that we have manufactured.
