Reverse Modeling and Preparation of Ankle Bone Based on Medical CT and SLM Technology
The bone reconstruction and manufacturing were realized based on medical CT and 3D printing technology.The original CT data of a patient's ankle bone were collected,the medical Mimics and Geomagic softwares were used to reconstruct the 3D model of the bone and optimize the bone surface respectively,the ankle bone model with a relatively smooth surface was obtained.The static analysis of the bone model shows that the model meets the mechanical requirements of the bionic bone under the biomechanical conditions of the human body structure.Through experiments,the optimized process parameters of SLM of TC4 titanium alloy were obtained,the laser power is 240 W,the scanning speed is 800 mm/s,the scanning spacing is 0.12 mm and the powder thickness is 0.05 mm.The 3D printing reverse manufacturing of the TC4 ankle bone was realized by using the parameters and the established ankle bone model.The shape and composition of the obtained product are good and meet the requirements of medical use.
