Abstract: Compared with traditional titanium alloy scaffolds, the mechanical properties of Ti-6Al-4V porous scaffolds fabricated by 3D printing are closer to natural bone tissue and have good biocompatibility, which is expected to become an ideal material for bone defect repair. In order to improve the biological properties of titanium alloy, various surface treatment technologies emerge as the times require. These treatment technologies can be divided into coating and non-coating method, and different surface treatment technologies have their own advantages and disadvantages. This paper reviewed the research progress of titanium alloy scaffolds and their surface treatment technologies.
