Abstract

This article introduces the design, methods, and use cases of a novel Gravity Augmented Additive Manufacturing (GAAM) approach to Fused Filament Fabrication (FFF) using a novel seven degree of freedom (DoF) delta robotic system. Capable of rotating parts and approaching the workpiece with the deposition head from user-specified or algorithm-determined angles, this system allows users the design freedom to create objects using less support material, while improving the performance of 3D printed components. Not only is time saved by reducing (or eliminating) support material, but components may be able to resist higher loading. Additionally, this system and the methods of operation described below allow users to create objects that are otherwise impossible or impractical to construct using traditional three axis FFF 3D printing, while maintaining compatibility with existing G-code preparation techniques. Finally, this more flexible 3D printing system has advanced applications in generating patient specific objects, which may benefit from more highly specialized toolpaths and design freedom afforded by this system.

重力增强熔丝制造增材制造

本文介绍了一种新型的重力增强增材制造（GAAM）方法的设计、方法和用例，该方法使用一种新型七自由度（DoF）德尔塔机器人系统来制造熔融丝（FFF）。该系统能够旋转零件，并使用沉积头从用户指定或算法确定的角度接近工件，使用户可以自由设计，使用更少的支撑材料创建物体，同时提高3D打印组件的性能。通过减少（或消除）支撑材料不仅节省了时间，而且组件可以抵抗更高的负载。此外，该系统和下面描述的操作方法允许用户创建使用传统的三轴FFF 3D打印不可能或不切实际的对象，同时保持与现有G码准备技术的兼容性。最后，这种更灵活的3D打印系统在生成患者特定对象方面具有先进的应用，这可能受益于该系统提供的更高度专业化的工具路径和设计自由度。
