Vat Photopolymerization Additive Manufacturing for Advanced Ceramics: Techniques, Multimaterial Strategies, and Applications

Vat photopolymerization additive manufacturing (VPP‐AM) technology has emerged as a pivotal technology for the precision manufacturing of advanced ceramics, owing to its unique design freedom, superior manufacturing accuracy, and excellent surface quality. However, traditional homogeneous single‐material ceramic components have revealed functional limitations, driving the transition of ceramic VPP‐AM from single‐material systems to multimaterial composite architectures. Multimaterial VPP‐AM enables the integrated fabrication of diverse ceramic materials, thereby producing components with comprehensive properties. Although various literature has reviewed VPP‐AM of single‐material ceramics, a summary regarding manufacturing strategies, cleaning mechanisms, and applications of multimaterial ceramics remains lacking. This review systematically summarizes the preparation strategies, applications, and recent advances in VPP‐AM for single‐material and multimaterial ceramic fabrication. Photopolymerization forming principles of ceramic components and their innovative applications for six representative single‐material ceramics VPP technologies are analyzed and discussed. Three core multimaterial ceramic manufacturing strategies, such as switching vat, dynamic fluidic control, and VPP hybridization are comprehensively elucidated. Cleaning methods and multimaterial interface design strategies are also introduced in detail. Prospective outlooks are provided regarding the existing technical bottlenecks and future development directions for multimaterial ceramic VPP‐AM, offering technical insights for the innovative design of high‐performance multifunctional composite ceramic devices.
