接受腔被认为是假肢组成中的一个重要元素。每个关节窝都是量身定制的设备，旨在适应患者残肢的独特几何形状。假肢接受腔的设计和制造传统上是手工过程，其依赖于使用巴黎石膏模型来捕获患者残肢的形状，然后依赖于工匠制造技术来制造接受腔。计算机辅助设计和制造技术克服了传统工艺的一些缺点，但假肢接受腔的最终制造仍然是手工进行的。快速成型（RP）是一种相对较新的制造技术，它直接从三维（3-D）计算机数据创建物理模型。以前对RP系统在假肢接受腔制造中的应用的研究主要集中在昂贵的高端技术上，这些技术已被证明过于昂贵。本文研究了一种更便宜的低端RP技术（称为3D打印）的使用。我们的调查是使用通常与快速生产原型相关的技术的初步方法，其中一些无法通过替代方法制造。在正常情况下，这些印刷部件是脆弱的，相对脆弱。然而，用3D打印制造的舒适的假肢接受腔已被用于与患者的初步装配。
The socket is considered an element of major importance in the makeup of a prosthesis. Each socket is a tailor-made device, designed to fit the unique geometry of the patient's residual limb. The design and manufacture of a prosthetic socket traditionally has been a manual process that relies on the use of plaster of Paris casts to capture the shape of the patient's residual limb and then artisan fabrication techniques to manufacture the socket. Computer-aided design and manufacturing technologies have overcome some of the shortcomings of the traditional process, but the final manufacture of the prosthetic socket is still performed manually. Rapid prototyping (RP), a relatively new class of manufacturing technologies, creates physical models directly from three-dimensional (3-D) computer data. Previous research into the application of RP systems to the manufacture of prosthetic sockets has focused on expensive, high-end technologies that have proven too expensive. This paper investigates the use of a cheaper, low-end RP technology known as 3-D printing. Our investigation was an initial approach to using a technology that is normally associated with producing prototypes quickly, some of which could not be manufactured by alternative means. Under normal circumstances, these printed components are weak and relatively fragile. However, comfortable prosthetic sockets manufactured with 3-D printing have been used in preliminary fittings with patients.
