【摘要】：目的:探讨3D打印踝足矫形器(AFO)临床应用的可行性,并希望能够降低打印成本,促进临床应用。方法:采用Artec三维扫描仪扫描患肢,利用软件Meshlab进行STL文件的表面处理。通过软件Instep将STL文件转换成STP文件。利用Abaqus软件,建立有限元模型,对AFO进行有限元分析。利用软件Evolve对AFO模型结构优化,去除多余的结构。最后通过3D打印机打印制作所需的AFO。结果:详细展示3D打印AFO的具体流程,有限元分析结果表明,AFO后部中间和两侧区域的应力明显高于其他区域,结构优化后AFO减少了17%的重量,两种材料打印的AFO轻便,打印成本也有降低。结论:本次研究成功地展示了3D打印AFO的临床应用流程,降低打印成本可以促进3D打印技术的临床应用。
[Abstract]:Objective: to explore the feasibility of 3D printing AFO for ankle foot orthosis and to reduce printing cost and promote clinical application. Methods: Artec 3D scanner was used to scan the affected limbs, and the surface of STL files was treated by software Meshlab. STL files are converted to STP files by software Instep. Using Abaqus software, the finite element model is established, and the finite element analysis of AFO is carried out. The software Evolve is used to optimize the structure of AFO model, and the redundant structure is removed. Finally, the AFO is produced by 3D printer. Results: the detailed process of 3D printing AFO was presented. The results of finite element analysis showed that the stress in the middle and both sides of AFO was significantly higher than that in other regions, the weight of AFO was reduced by 17% after structural optimization, and the AFO of two kinds of materials was easy to print. Printing costs have also been reduced. Conclusion: this study successfully demonstrated the clinical application process of 3D printing AFO, which can promote the clinical application of 3D printing technology by reducing printing cost.
