Surface treatment of 3D printed porous Ti6Al4V implants by ultraviolet photofunctionalization for improved osseointegration

Three-dimensional (3D)-printed porous Ti6Al4V implants play an important role in the reconstruction of bone defects.However, its osseointegration capacity needs to be further improved, and related methods are inadequate, especially lacking customized surface treatment technology.Consequently, we aimed to design an omnidirectional radiator based on
