Abstract

Abstract

Titanium and titanium alloys possess superior biocompatibility, corrosion resistance, and mechanical properties, making them among the few metal materials safe for implantation in the human body. They are widely used in biomedical applications, including implants, dentistry, surgical instruments, stents, tissue engineering, and in vitro medical devices. Biomedical implants made of titanium and titanium alloys are traditionally manufactured through subtractive and forming processes. In recent years, with the advancement of additive manufacturing (3D printing) technology, biomedical implants can now be directly fabricated using data from medical imaging methods, enabling the three-dimensional additive connection of titanium materials to produce components. Selective laser melting (SLM), electron beam melting (EBM), and directed energy deposition (DED) are the primary technologies for the additive manufacturing of titanium components. The most commonly used additive manufacturing titanium materials in biomedical applications are commercially pure titanium (CP-Ti) and titanium alloys (Ti-64). Compared to traditional manufacturing methods, the key advantages of additive manufacturing lie in its multidimensional and personalized production capabilities, along with greater reproducibility. To update the latest advancements in research on titanium and titanium alloy biomedical implants, this paper reviews titanium and titanium alloys, 3D printing methods, and their applications in biomedical implant. It discusses and summarizes the latest developments in 3D-printed titanium implants and explores future research directions for titanium-based 3D-printed biomedical implants.
