ABSTRACT Current design methods of individualized insoles are confronted with much-repeated work and are over-reliance on experiences. To tackle these problems, parametric modeling and selective laser sintering (SLS) were integrated for automatically generating personalized insoles in this study. 3D scanning was first used to achieve an individual’s foot model and then an innovative parametric modeling program with an automatic line drawing module based on Grasshopper was developed. Additionally, both personalized insoles and flat insoles were manufactured via SLS technology and their performances were evaluated with finite element analysis and a Footscan system. The results show that the proposed parametric method of individualized insoles largely reduces the workload in comparison to traditional design, and can conveniently regulate the insole design for agreeable foot comfort. And the developed customized insoles with complex array structure can be successfully manufactured with SLS technology. Additionally, the personalized insole can reduce the peak contact pressure by 30% compared with the flat insole, and increase the strength and the durability of the insole, which is mainly attributed to the foot-fitting surface and the adopted array structure. The advantages and potential applications of the proposed parametric modeling method coupled with SLS technology were also discussed.

基于3D扫描和选择性激光烧结的个性化鞋垫参数化建模与性能分析
摘要 当前个性化鞋垫的设计方法面临着重复工作和过度依赖经验的问题。为了解决这些问题,本研究将参数化建模和选择性激光烧结 (SLS) 相结合,以自动生成个性化鞋垫。3D 扫描首先用于实现个人的足部模型,然后开发了基于 Grasshopper 的具有自动绘制线条模块的创新参数化建模程序。此外,个性化鞋垫和平底鞋垫均通过 SLS 技术制造,并通过有限元分析和 Footscan 系统评估其性能。结果表明,与传统设计相比,所提出的个性化鞋垫参数化方法大大减少了工作量,并且可以方便地调节鞋垫设计,以获得舒适的脚感。开发出的具有复杂阵列结构的定制鞋垫可以通过SLS技术成功制造。此外,个性化鞋垫比平底鞋垫可降低峰值接触压力30%,增加鞋垫的强度和耐用性,这主要归功于贴脚面和采用的阵列结构。还讨论了所提出的参数化建模方法与 SLS 技术相结合的优势和潜在应用。增加鞋垫的强度和耐用性,这主要归功于贴脚面和采用的阵列结构。还讨论了所提出的参数化建模方法与 SLS 技术相结合的优势和潜在应用。增加鞋垫的强度和耐用性,这主要归功于贴脚面和采用的阵列结构。还讨论了所提出的参数化建模方法与 SLS 技术相结合的优势和潜在应用。
