Bai Yuchao is a Senior Research Fellow at the Department of Mechanical Engineering in National University of Singapore. He received his Bachelor's degree and PhD from South China University of Technology in 2013 and 2018, respectively. He has been engaged in the development of additive manufacturing technology and manufacturing process since 2013. His main research interest includes laser metal additive manufacturing and post-processing, multi-material manufacturing, ultra-precision post-processing, and hybrid manufacturing processing for comprehensive research in the field. He is the topic editor of the journal Coating, and the author of more than 40 peer-reviewed scientific papers on metal additive manufacturing and post-processing. He has co-authored a book "Powder-bed laser melting additive manufacturing technology" (Associate Editor, Chinese Edition). His expertise and innovation in the development of additive manufacturing machines and additive/subtractive hybrid machine process designs have yielded a number of patents, where 50 were successfully patented by China and Japan, and four are pending Patent Cooperation Treaty (PCT). Several successful patents have been applied in commercial 3D printers. His patent on additive/milling hybrid manufacturing technology obtained the Silver Patent Award and the national Invention-Entrepreneurship Gold Award. Currently, he is serving as a reviewer for more than a dozen international SCI-indexed journals.

Zhang Jiong is a research fellow at Department of Mechanical Engineering, National University of Singapore (NUS). He obtained his PhD from the Department of Mechanical Engineering at NUS and an M.S. (mechanical engineering) from Shanghai Jiao Tong University and a B.A. (mechanical engineering) from Zhejiang University. His research focuses on post-processing for additive manufacturing, internal polishing, and ultraprecision machining. He is particularly interested in developing and modelling post-processing techniques for additively manufactured components, including support removal and surface quality enhancement. He has published more than 23 peer-reviewed journal papers in top-tiered journals such as Additive Manufacturing, Rapid Prototyping Journal, International Journal of Machine Tools and Manufacture, Materials and Design, Precision Engineering, etc. He has also published nine conference papers and one book chapter. In addition, he is a member of euspen's International Scientific Committee since 2021 and has been serving as an active reviewer for several SCI-indexed journals.
