AI中文摘要：
本文介绍了Print&Fold工具，该工具可实现FDM 3D打印复杂模型，同时减少时间和材料消耗并保持形状精度。本研究的关键是一种折叠算法，可将3D模型内部可折叠的面展平。传统折叠技术通常会离散化目标模型的表面，从而制造出低保真度的对应模型，而我们的方法可在物理打印中保留表面特征。我们的设计工具允许用户将3D模型展开为可FDM打印的平面，之后手动将其折叠为目标形状。我们展示了多种应用，并评估了一系列3D模型的材料和时间节省情况。
英文摘要：
This paper introduces Print&Fold, a tool to allow FDM 3D printing of complex models with less time and material while preserving shape accuracy. Key to this work is a folding algorithm that planarizes foldable faces internal to the 3D model. While folding techniques typically discretize a target model's surface, thereby fabricating low fidelity counterparts, our method preserves the surface features in the physical print. Our design tool allows users to unfold 3D models to be FDM-printed flat before manually folding these into their target shapes. We showcase a variety of applications and evaluate the material and time savings across a range of 3D models.
