Prof. Hui-Suk Yun from Korea Institute of Materials Science, the 2025 Lee Hsun Lecture Award recipient, visited the Institute of Metal Research, Chinese Academy of Sciences (IMR, CAS), from October 23 to 24 for academic exchange.
During her visit, Prof. Hui-Suk Yun delivered an academic lecture entitled "New Challenges with Ceramic Additive Manufacturing Technology" to IMR researchers and postgraduate students.
Additive manufacturing (AM) is a forming process that builds three-dimensional objects by successively depositing two-dimensional layers of material based on digital information from computer-aided design files, eliminating the need for part-specific molds. The application of this technology in the field of ceramics has attracted significant attention, as it effectively overcomes technical bottlenecks in controlling complex three-dimensional structures and has achieved remarkable progress over the past decade.
In her lecture, Prof. Hui-Suk Yun focused on the challenges faced by ceramic additive manufacturing technology. She explained that stereolithography, as a representative ceramic AM technology, uses a projector light source to selectively cure photosensitive polymers blended with ceramic particles, thereby fabricating complex 3D components with high structural precision and accuracy. Despite extensive research exploring the application of stereolithography in manufacturing complex 3D ceramic devices, there remain notable limitations and challenges. Among these, optimizing the photocurable ceramic slurry is a key prerequisite, requiring comprehensive consideration of the structural requirements of the final product, the density and refractive index of raw materials, color, and subsequent heat treatment conditions. Only through meticulous design can ceramic devices with high structural integrity and dimensional accuracy after sintering be achieved. Prof. Hui-Suk Yun also provided a detailed introduction to the latest research progress made by her team in related areas.
The lecture received enthusiastic responses from attending researchers and students, who engaged in in-depth discussions with Prof. Hui-Suk Yun on relevant topics.
During her visit, Prof. Hui-Suk Yun also held a series of discussions with researchers from the Ceramic Materials Research Division focusing on ceramic additive manufacturing and its applications.
Prof. Hui-Suk Yun's research encompasses the entire technological process of ceramic additive manufacturing. She is dedicated to the development of biomedical materials, particularly porous biomaterials for tissue engineering. To date, she has obtained 57 domestic Korean patents (43 granted) and 18 international patents (11 granted), published over 80 papers, delivered 36 invited talks, and enjoys significant international academic influence. Prof. Hui-Suk Yun has achieved multiple pioneering accomplishments in the field of additive manufacturing and holds important positions in several academic organizations: Business Operation Director of the Korean Ceramic Society (2016-2019); Chair of the Kingery Award Committee of The American Ceramic Society (ACerS) (2021-2023); Chair of the International Committee of ACerS Engineering Ceramics Division (since 2021); Vice Chair of the Korea Nano Technology Conference (2022, 2023); Chair of ACerS Korea Chapter and Associate Editor of Bioactive Materials (since 2023); Member of the ACerS Nominating Committee, Vice President of the Korean Materials Research Society, and Vice President of the Korean Society for Biomaterials (since 2024); and President of the Korean Society of Medical 3D Printing (since 2025). She was elected Fellow of The American Ceramic Society in 2024.
