The use of digital manufacturing for the construction of orthosis and prostheses has become common since the popularization of 3D printers and the advent of Industry 4.0. Furthermore, due to the fact that the manufacture of orthosis is interactive and for personal use, generic production is difficult. In this sense, the large-scale production of these products lacks of improvements, standardization of processes and production optimization. An aggravation of this is the recent social distance due to the COVID-19 pandemic, which makes the use of temporary orthosis made in 3D printers to have a recent growth. Parallel to this, the use of multi-lattice inner structures for internal structuring of prints has also been increasing and taking on a more consolidated form. This article aims to present the multi-lattice optimization as a solution to this problem, in order to reduce material waste while maintaining the mechanical behavior of printed parts.
自3D打印机普及和工业4.0出现以来，数字制造在矫形器和假肢制造中的应用已变得很普遍。此外，由于矫形器的制造具有交互性且供个人使用，批量生产很困难。从这个意义上说，这些产品的大规模生产缺乏改进、流程标准化和生产优化。更糟糕的是，近期因新冠疫情而保持社交距离，这使得3D打印临时矫形器的使用量最近有所增长。与此同时，用于打印内部结构的多晶格内部结构的使用也在增加，并呈现出一种更稳固的形式。本文旨在提出多晶格优化作为解决此问题的方案，以减少材料浪费，同时保持打印部件的机械性能。
