Abstract
A manufacturing method for a bone implant is provided. The manufacturing method includes the following steps. Firstly, an implant body is provided, wherein the implant body is made of metal comprising titanium or an alloy comprising titanium. Then, a processing apparatus is provided, wherein the processing apparatus comprises an ultrafast laser source, a first wave plate and a second wave plate. Then, ultrafast laser light is emitted by the ultrafast laser source to the implant body through the first wave plate and the second wave plate to form a plurality of microstructures and a titanium dioxide film, wherein each microstructure has a height and a weight, the weight is less than 2 micrometers, and the height is less than 1 micrometer.
