Development of 3D printing personalized orthoses manufacturing technology

摘要:

逆向工程（reverse engineering, RE）是个性化矫形器制作的重要部分，根据测量数据重构患处 3D 模型，通过计算机辅助设计（computer aided design, CAD）方法设计矫形器，再利用快速成型技术（rapid prototyping, RP）制作。3D 打印个性化外固定矫形器目前是“医工”交叉学科研究的热门领域，具有高贴合度、轻便透气、定制结构等优点，有助于功能恢复。近年来，对于个性化矫形器制造流程的效率、成本及舒适度的研究逐年增加，本文侧重于 RE 方法，按照制造流程从光学扫描、 CAD 建模、镂空最后到 3D 打印成型的相关技术优化研究进展进行概述。

Abstract:

Reverse engineering (RE) is an important part of the manufacturing of personalized orthoses, which including reconstruct- ing 3D model of the involved area according to the measured data, the orthoses are designed by computer aided design (CAD) method, and then made by rapid prototyping technology (RP). The 3D printing personalized orthoses are currently popular interdisciplinary research in ‘medical-engineering’, which with advantages of suitable, light weight, customized structure can be helpful for functional recovery. In re- cent years, in order to accelerate the application, the research on the efficiency, cost and comfort of personalized orthoses manufacturing has been increasing year by year. Therefore, this article focuses on the RE method, and summarizes the research on related technology im- provement of manufacturing process from optical scanning, CAD modeling, hollow-carved design to RP.
