Representative work: Stereolithography additive manufacturing (SLAM) has exhibited great potential for fabricating advanced ceramic objects with geometrically complicated structures for use in diverse fields owing to its excellent feature resolution and high surface quality. However, it is difficult to fabricate advanced ceramic parts with desired performance for structural and functional applications using this technology, because numerous binders used in ceramic SLAM must be removed by thermal debinding (TD), resulting in various defects generation and long processing period. In this review, we first focus on the raw materials used to create photocurable ceramic suspensions that greatly affect the TD process. A novel method has been developed to fabricate SiC/Al composites by the combination of laser powder bed fusion (LPBF) and vacuum-pressure infiltration. The effects of the SiC particle size distribution and pre-oxidation on the microstructu
