In recent years, personalized fabrication has received considerable attention because of the widespread use of consumer‐level three‐dimensional (3D) printers. However, such 3D printers have drawbacks, such as long production time and limited output size, which hinder large‐scale rapid‐prototyping. In this paper, for the time‐ and cost‐effective fabrication of large‐scale objects, we propose a hybrid 3D fabrication method that combines 3D printing and the Zometool construction set, which is a compact, sturdy and reusable structure for infill fabrication. The proposed method significantly reduces fabrication cost and time by printing only thin 3D outer shells. In addition, we design an optimization framework to generate both a Zometol structure and printed surface partitions by optimizing several criteria, including printability, material cost and Zometool structure complexity. Moreover, we demonstrate the effectiveness of the proposed method by fabricating various large‐scale 3D models.

ZomeFab：使用 Zometools 实现经济高效的混合制造

近年来，由于消费级三维（3D）打印机的广泛使用，个性化制造受到了广泛关注。然而，这种 3D 打印机存在生产时间长和输出尺寸有限等缺点，阻碍了大规模快速成型。在本文中，为了节省时间和成本效益地制造大型物体，我们提出了一种结合 3D 打印和 Zometool 构造集的混合 3D 制造方法，这是一种紧凑、坚固且可重复使用的填充制造结构。所提出的方法通过仅打印薄的 3D 外壳显着降低了制造成本和时间。此外，我们设计了一个优化框架，通过优化多个标准，包括可印刷性、材料成本和Zometool结构复杂性。此外，我们通过制造各种大型 3D 模型证明了所提出方法的有效性。
