用多轴3D打印实现非平面双层壳结构，轻量化且可拼装。
Non-planar 3D Printing of Double Shells
- 基于横向条带网络生成可打印分区，分块打印后组装
- 支持不同尺度与复杂度曲面，实测验证可行性
- 适合建筑原型、幕墙等需要轻质结构的场景
我们提出一种基于多轴熔融沉积建模（FDM）机器人3D打印的方法，用于在横向方向上制造双层壳结构。壳体结构具有轻量化、壁薄、快速构建和材料用量少的特点，在原型设计和建筑领域广泛应用，如立面板、混凝土模具或全尺寸亭子。我们采用现有方法生成的横向条带网络作为底层表示，提出将这些网络转化为可打印分区的方案。每个分区独立打印后组装成双层结构。文中详细说明了各部件打印及后续装配过程的技术规格与工作流程。通过数字模拟与实物制作结果，展示了该方法在不同尺度和几何复杂度表面下的通用性与鲁棒性。
原文摘要 · Abstract (English)
We present a method to fabricate double shell structures printed in trans-versal directions using multi-axis fused-deposition-modeling (FDM) robot-ic 3D printing. Shell structures, characterized by lightweight, thin walls, fast buildup, and minimal material usage, find diverse applications in pro-totyping and architecture for uses such as façade panels, molds for concrete casting, or full-scale pavilions. We leverage an underlying representation of transversal strip networks generated using existing methods and propose a methodology for converting them into printable partitions. Each partition is printed separately and assembled into a double-shell structure. We out-line the specifications and workflow that make the printing of each piece and the subsequent assembly process feasible. The versatility and robust-ness of our method are demonstrated with both digital and fabricated re-sults on surfaces of different scales and geometric complexity.
