论文摘要
在本文中，我们介绍了一种方法，可以通过上拉网折叠2D纸快速创建3D几何形状。鉴于3D结构，我们使用启发式算法将其网格展开到平面2D纸中，并用餐具和透水孔填充它们。我们开发了一个基于Web的仿真工具，该工具将用户的3D网格转换为可制造的2D纸。在激光切割板并通过这些透过的孔形成下拉网后，将螺纹拉开板将使用单个自由度折叠到3D结构中。我们介绍了制造过程并建立了各种原型，这些原型表明该方法可以快速创建适用于低效率原型制作的几何形状广度，这些原型既具有负载且在一系列尺度上具有载荷又是美学。未来的工作将扩大可用几何形状的广度，并评估我们的原型维持结构负载的能力。
In this paper, we introduce a method to rapidly create 3D geometries by folding 2D sheets via pull-up nets. Given a 3D structure, we unfold its mesh into a planar 2D sheet using heuristic algorithms and populate these with cutlines and throughholes. We develop a web-based simulation tool that translates users' 3D meshes into manufacturable 2D sheets. After laser-cutting the sheet and feeding thread through these throughholes to form a pull-up net, pulling the thread will fold the sheet into the 3D structure using a single degree of freedom. We introduce the fabrication process and build a variety of prototypes demonstrating the method's ability to rapidly create a breadth of geometries suitable for low-fidelity prototyping that are both load-bearing and aesthetic across a range of scales. Future work will expand the breadth of geometries available and evaluate the ability of our prototypes to sustain structural loads.
