As the current mainstream human implants

it is of great significance to investigate the corrosion behavior of titanium alloys in various human environments. The characteristics and advantages of different additive manufacturing technologies were reviewed

and the corrosion behavior of titanium alloys prepared by selective laser melting and electron beam melting in different human environments were mainly discussed

such as oral cavity and hard bones

and some specific simulated human environments as well as experimental conclusions were summarized. On this basis

the problems that need to be improved in the applications of additive manufactured titanium alloys in the human environment were proposed

and large-scale applications and prospects were predicted.
