Seminar Abstract

Metal 3D printing involves manufacturing techniques that add material to produce metallic components, typically layer by layer. This technology has been recognized as a key enabler in a wide range of applications in the automotive, aerospace, defense, and medical industries. Extensive research has been conducted on metal 3D printing over the last two decades, focusing primarily on identifying processing windows for various material systems and their effects on the properties of printed objects to achieve quality parts. However, the development of advanced equipment and systems has received comparatively less attention, despite its importance. In this context, we have conducted a comprehensive study on metal 3D printing systems and process technology, specifically focusing on powder bed fusion (PBF) and direct energy deposition (DED), to enhance the functional performance of the final products. Our research has emphasized the prototype development of printing systems and their core modules, including optical systems, processing heads, powder feeding systems, hybrid tooling, protective atmosphere systems, and process monitoring and control software. This seminar discusses our recent advancements in metal 3D printing systems and processes.

    Speaker's Biography 

    Joon Phil Choi received his Ph.D. degree from Hanyang University, Republic of Korea, in 2015. He served as a postdoctoral researcher at the Department of Mining and Materials Engineering, McGill University, Canada, from 2016 to 2018. Additionally, he worked as a postdoctoral fellow at the Singapore Centre for 3D Printing and School of Mechanical and Aerospace Engineering, Nanyang Technological University, Singapore, from 2019 to 2021. His research interests focus on enabling powder processing and 3D printing (or additive manufacturing) of advanced materials, as well as creating strategic value for the industry through advanced manufacturing techniques. In 2021, Dr. Choi joined the Korea Institute of Machinery & Materials (KIMM) to continue his research in the areas of materials and processing for metal 3D printing applications. He has co-authored over 40 peer-reviewed articles in the field of metal powder processing and 3D printing, and he is also a co-inventor of several patents related to materials processing technologies.
