Abstract
This paper presents a systematic review of biomedical Ti alloys fabricated through additive manufacturing. It begins with an overview of the development of Ti metals and their applications in biomedical fields, particularly in orthopedic and dental implants. The review highlights recent advancements, such as the incorporation of porous structures. Key aspects of additive manufacturing for biomedical Ti alloys are explored, including material characteristics, preparation parameters, solidification behavior, and post-heat treatments, with emphasis on their effects on microstructure and material properties. This paper further summaries the current states of biomedical standards for Ti alloys, and concludes with a discussion of future trends, opportunities, and challenges in the additive manufacturing of biomedical Ti alloys, including advancements in material innovation, process optimization, and the integration of personalized implants. This review aims to provide valuable insights into the ongoing developments and future directions for additive manufacturing biomedical Ti alloys.
