Summary The technology LIMBER aims to provide is an all-inclusive service that enables the rapid and scaled-up manufacturing of customized prosthetics on-demand for amputees. The World Health Organization (WHO) estimates that out of the tens of millions of amputees worldwide, only 5% to 15% have access to prosthetics or other assistive devices. The lack of widespread availability is because most rehabilitation devices are designed and hand-crafted by prosthetists through a complex and time-consuming process. This Phase I SBIR proposal will confirm the feasibility of LIMBER’s prosthetic design and manufacturing system that overcomes the custom-care and cost barriers by combining the latest in 3D scanning, digital design, and additive manufacturing technologies to increase the capacity of professional prosthetists and provide access to affordable and functional ‘unibody’ transtibial prosthetic limbs that are comfortable, lightweight, and automatically fabricated. LIMBER’s process leverages the structured light scanning capability embedded in smartphones to create a digital twin of an amputee from the waist down. Scanning can be accomplished in minutes by a prosthetist or trained technician, further improving efficiency and alleviating bottlenecks of the conventional process. The data is then transferred to LIMBER’s cloud, where our skilled prosthetists transform it into a personalized single-piece (socket, pylon, and ankle-foot combined) prosthetic device that is 3D printed. After working with 15 lower-limb amputees, our preliminary findings include a reduction in the average cost, weight, and time of production by 79%, 55%, and 66%, respectively.

概括 LIMBER 旨在提供的技术是一种包罗万象的服务，能够实现快速、规模化的制造 世界卫生组织 (WHO) 估计，有数十名截肢者需要定制假肢。 全球有数百万截肢者，其中只有 5% 至 15% 能够使用假肢或其他辅助器具。 广泛使用是因为大多数康复设备都是由假肢师通过专业技术设计和手工制作的 复杂且耗时的过程。 第一阶段 SBIR 提案将确认 LIMBER 假肢设计和制造系统的可行性 通过结合最新的 3D 扫描、数字设计和增材制造技术，克服了定制服务和成本障碍 制造技术，以提高专业假肢师的能力，并提供负担得起的和 功能性“一体式”经胫假肢，舒适、轻便且自动制造。 LIMBER 的流程利用智能手机中嵌入的结构光扫描功能来创建 假肢师或训练有素的技术人员可以在几分钟内完成截肢者腰部以下的扫描。 提高效率并缓解传统流程的瓶颈 然后将数据传输至 LIMBER。 云，我们熟练的假肢师将其转变为个性化的单件（插座、支架和踝足组合） 在与 15 名下肢截肢者合作后，我们的初步发现包括： 平均成本、重量和生产时间分别减少了 79%、55% 和 66%。
