　　报告内容：Additive manufacturing (AM) is a fabrication process that used digital information from a computer-aided design file to stack 2D layers of various materials to produce a 3D object, without requiring any part-specific tooling. AM technologies have attracted much attention in various fields such as medicine, automotive, aerospace, consumer, and other industrial applications. However, there are still limitations in both selection of materials as well as controlling part performance. In the former case, polymers and metals are typically used as materials for high precision AM whereas the technology for ceramics is comparatively inadequate yet. In the latter case, functionality of 3D structure was controlled only by designing 3D architectures, however we can expect much advanced functionality by using multi-materials for AM process. To this purpose, our group has developed a novel digital light processing for multi-ceramic additive manufacturing. The fabrication system and processing has been successfully optimized for various types of materials. We could co-print multi-component in one structure using less amount of ceramic slurry with high resource efficiency. We could control cross-contamination between multi components by adapting novel washing process. We believe that this new technology may provide big turning point to overcome limitation of traditional ceramic forming process. 

　　  

个人简介：Hui-suk Yun holds a Ph. D. in Materials Science Engineering from the University of Tokyo, Japan. She completed her post-doctoral research at the National Institute of Advanced Industrial Science and Technology (AIST, Japan) and then began working as a lecturer at the Consolidated Research Institute for Advanced Science and Medical Care at Waseda University, Japan. Currently, she is the head of the Department of Advanced Biomaterials Research at the Korea Institute of Materials Science (KIMS) and a professor at the University of Science & Technology (UST) in the Department of Materials Science. Furthermore, she is an advisory committee member for the Ministry of Science and ICT, Korea and a medical devices committee member for the Ministry of Food and Drug Safety, Korea. She was also working for the Korea government as a deliberative council member on the Presidential Advisory Council of Science and Technology. Her research interests include bioceramics in tissue engineering, porous materials, and technologies for ceramic additive manufacturing, including materials, processes, and systems. She has 40 domestic patents, 8 international patents, and has published over 75 SCI papers. She has also written 7 technology transfer contracts relating to ceramic additive manufacturing. Evidently, she is an accomplished academic who has received many honors, such as the 2023 plenary award from Engineering Ceramic Division of American Ceramic Society, the best performance award of running royalty from the Korean Intellectual Property Office, in 2021, the 2021 Global Ambassador Award and 2020 ECD Jubilee Global Diversity Award from the American Ceramic Society, the 100 Most Distinguished Researchers Achievement from the Ministry of Science and ICT, and the World’s Top Technology Prize from the Korea Institute of Materials Science.
