Abstract
This dissertation proposes a multi-material co-sinterable ceramic monolith fabrication method based on additive manufacturing, capable of producing ceramic monoliths with internal flow channel structures and demonstrating the potential for high-temperature applications. The research utilizes powder printing and layer-by-layer pressing techniques to address the performance limitations imposed by sealing materials in existing high-temperature ceramic applications. The study is grounded in the low-temperature sintering of high-density YSZ ceramic powder and verifies the co-sinterability of multiple material powders. It further explores the selection of fugitive materials and strategies for optimizing springback behavior in dry pressing. Additionally, a nozzle printing technology for dry ceramic powders is developed. Finally, an experimental platform is established to validate the feasibility of the Dry Powder Printing Additive Manufacturing (DPP-AM) technique for fabricating ceramic monoliths with micro-scale flow channels. The findings of this research have the potential to advance ceramic industry applications in high-temperature heat exchangers and ionic transport devices.
