Abstract
Disclosed herein is a method for manufacturing an implant that is to be surgically inserted in vivo, such as in an artificial knee or artificial hip. According to the method, the porous layer contains pores that have a vertically curved shape with a radius of 100 to 300 μm, thus allowing a bond to grow into the pores to enhance bond adhesion, and an interconnection space is formed between turning points in adjacent unit base layers to increase the ratio of interconnection between pores, whereby bones are allowed to grow into the pores to increase bone adhesion.
