Abstract Electron beam powder bed fusion (EB-PBF) is particularly suitable for rapid forming of high-activity and high-melting-point medical metal materials due to its advantages, including high energy density, high energy utilization efficiency, fast scanning speed, low forming stress, and high cleanliness in a vacuum environment. It has been widely applied in the field of orthopedic implants with trabecular structures. This paper comprehensively reviews the technical characteristics of EB-PBF, the current development status of EB-PBF equipment, and its research and application progress in manufacturing titanium alloy and porous tantalum. Additionally, it discusses the opportunities and challenges for medical metal materials fabricated by EB-PBF in China.
