预制矫形器目前设计用于适应各种患者，因此它们不能提供个性化的舒适度和功能。从上述两个角度来看，定制矫形器都优于预制矫形器。然而，制作定制矫形器是一个费力且耗时的手动过程，需要由熟练的矫形师完成。此外，对预制和定制矫形器的调整都是以定性的方式进行的。因此，舒适性和功能可能会受到相当大的影响。用于制造患者专用矫形装置的计算机化技术有可能提供卓越的舒适度，并允许改变标准设计以满足每个患者的特定需求。在本文中，3D 激光扫描与快速原型制作相结合，打造出患者专用的矫形器。设计了一种新颖的流程，利用患者解剖结构的患者特定表面数据作为数字输入，使用计算机辅助设计 (CAD) 软件将表面数据处理为最佳形式，然后将 CAD 软件的数字输出下载到快速原型机进行制造。两个 AFO 快速原型化以演示所提出的流程。佩戴 AFO 的受试者的步态分析数据表明，快速原型 AFO 的性能与预制聚丙烯设计相当。与预制的 AFO 相比，本研究中制造的快速原型矫形器能够很好地贴合受试者的解剖结构，同时提供类似的功能（即对步态生物力学的机械效应）。快速制造能力令人感兴趣，因为它有可能减少制造时间和成本，特别是在需要更换矫形器时。
Prefabricated orthotic devices are currently designed to fit a range of patients and therefore they do not provide individualized comfort and function. Custom-fit orthoses are superior to prefabricated orthotic devices from both of the above-mentioned standpoints. However, creating a custom-fit orthosis is a laborious and time-intensive manual process performed by skilled orthotists. Besides, adjustments made to both prefabricated and custom-fit orthoses are carried out in a qualitative manner. So both comfort and function can potentially suffer considerably. A computerized technique for fabricating patient-specific orthotic devices has the potential to provide excellent comfort and allow for changes in the standard design to meet the specific needs of each patient. In this paper, 3D laser scanning is combined with rapid prototyping to create patient-specific orthoses. A novel process was engineered to utilize patient-specific surface data of the patient anatomy as a digital input, manipulate the surface data to an optimal form using Computer Aided Design (CAD) software, and then download the digital output from the CAD software to a rapid prototyping machine for fabrication. Two AFOs were rapidly prototyped to demonstrate the proposed process. Gait analysis data of a subject wearing the AFOs indicated that the rapid prototyped AFOs performed comparably to the prefabricated polypropylene design. The rapidly prototyped orthoses fabricated in this study provided good fit of the subject's anatomy compared to a prefabricated AFO while delivering comparable function (i.e. mechanical effect on the biomechanics of gait). The rapid fabrication capability is of interest because it has potential for decreasing fabrication time and cost especially when a replacement of the orthosis is required.
