【 摘 要 】

Bone defect caused by trauma and tumors is an important problem to be solved in orthopaedic clinic. Bone defects caused by various reasons have different shapes. In this paper a model of bone defect was created by 3D printing technology, which was tailor-made for doctors to simulate the bone defect before operation. Firstly, CT files of bone defect were imported into the Mimics medical image control system, then the pathological model was formed by image processing and three-dimensional reconstruction. Secondly, the 3-matic forward engineering software was ultilized to realize the design model of bone defect repair by describing, mirror image and bone repair. Thirdly, after processing the design model with Cura chip software, the PLA macromolecule material was used to make the physical object by 3D printer. By researching the design method, forming quality, printing speed, structure and performance parameters, researchers explored the manufacturing technology of 3D printing products for bone defect.
