Customized 3D-printed medical implants are becoming more common, and a new study has taken this technology to the next level. Researchers at Naton Biotechnology have developed the world's first laser 3D-printed total knee implant, which has received official approval from China's National Medical Products Administration as an innovative medical device. The study focused on improving the strength and consistency of cobalt-chromium-molybdenum (CoCrMo) alloy implants made using laser powder bed fusion (LPBF), a 3D printing process. The team discovered and corrected inconsistencies in the structure of the material by optimizing heat treatment, ensuring the final implants are stronger, more reliable, and...
