Preliminary Study On Rapid Prototyping To Prepare Biomimetic Model Of Aortic Arch

Objective:To create an anatomical correct 3D rapid prototyping (RP) model for a volunteer’s aortic arch dimensional microscopic data and demonstrate Prove the feasibility of the use of rapid prototyping consistent with the human anatomy of the aortic arch model prepared by Medical Imaging Technology Information. To understand the relevant principles of rapid prototyping, find the best method of preparing tissue engineering scaffolds and materials. investigate the significance of aortic arch model for surgical planning. To make the early preparations for the mannufacture of individualize artificial vascular stents and 3D printing with biological tissue or organ.Methods:Based on the extracted 3D contour image from volunteer’s chest CT data, the custom-made artificial aortic arch was designed with mimics 10.01 software and form 3D printing STL file. And then a aortic arch model was printed out by 3D printer.Results: The data acquired by CT scanner can be rapidly prototyped after being edited with Mimics 10.01 software and directly used by 3D printing system to construct a aortic arch model. Rapid prototyping methods include SLA, SLS, LOM, FDM, etc. Depending on the different chemical properties of the material, rapid prototyping materials can be divided into a resin material, paraffin materials, metal materials, ceramic materials, composite materials and biomaterials. ABS material aortic arch model can be used preoperative planning, can not replace the aortic arch bracket.Conclusion:The artificial 3D aortic arch model has significance in surgical planning and great help for the mannufacture of individualize artificial vascular stents and 3D printing with biological tissue or organ.
