Advances and Prospects on Additive Manufacturing Used for Medical Implants

Additive manufacturing (AM) is commonly used in the automotive, medical, and aerospace industries. With people concentrating more on healthcare, AM technology provides a more complex and free product structure, a growth spike in the application of AM can be seen in this field. Therefore, this paper focuses on a specific field of the medical industry, implants. This paper focuses on the latest improvements in AM used for implant production. Based on the relevant research reported on the Web of Science and Elsevier over the past five years, this article introduces the principles of the most widely used 3d printing technology for implant fabrication. It discusses the reasons for their successful use in this field. The existing typical technical routes and their advantages and limitations are summarized. This research also shows the latest advancements in those technologies. Based on their current characteristics and situations, this study gives some suggestions about potential further improvements and development prospects. This study provides an in-depth analysis of AM in the field of implants in the industry and points out the development direction of AM in the medical field in the future.
