A Software Method to Model and Fabricate the Defective Bone Repair Bioscaffold Using in Tissue Engineering

摘要

In this paper, biologic properties and physical properties of the bioscaffold are studied. The requirements of the model of defective bone repair bioscaffold are proposed. Then, a new modeling method is presented, which can construct a defective bone repair bioscaffold 3d digital model that has the macro-shape and macro-pores. This method combines the image processing technology, 3d-reconstructing technology, and a new hole filling method, in which a mapping method is developed. It can be used in both symmetrical and unsymmetrical defective bone. By programming, this method was successfully implemented and the repair bioscaffold 3d digital model was constructed. Through RP process, using polymeric blends, the physical model was obtained, which meets the requirements of the bioscaffold.
