Abstract：HA /PU composites were synthesized by in -situ polymerization with nano -hydroxyapatite as reinforcement and polyu-rethane prepolymer as matrix.Based on CT data,the three -dimensional model of proximal femur was reconstructed directly by Mimics software.The 3 -D model was then converted to STL format file which was inputted to 3 -D printing machine to manufacture the entity model using ABS material as substrate material.The individualized proximal femur implant of HA /PU material was produced by pou-ring the HA /PU prepolymer matrix into the silicon mold that had been previously prepared by silicone rubber mold making technology. We introduce a novel technology to overcome the aforementioned disadvantage of implants mismatching to individual needs in volume production and provide technical support for manufacturing high value -added artificial bone.
