本研究提出一种全新的天基建造方法，利用微重力环境下的液体自组织作为生成式设计与制造的原理。基于LiquiFab方法，我们展示了传统上依赖复杂增材制造的极小曲面结构，如何通过可编程边界条件塑造的流体界面物理特性直接生成。我们提出一套从模拟到制造的工作流程，包含集成于Grasshopper/Rhino的边界驱动极小曲面求解器，以及在模拟微重力的中性浮力环境中运行的实验系统。该系统可生成具有可调几何形状与厚度的可定制Schwarz-P启发式结构，展示了一种材料高效、在轨制造的可扩展路径。为验证其在真实微重力环境下的性能，国际空间站计划于2027年第一季度开展飞行实验，本文详细阐述了该实验所需的额外考量因素。
英文摘要
This work advances a fundamentally new approach to space-based construction by using liquid self organization in microgravity as a generative design and fabrication principle. Building on the LiquiFab method, we demonstrate how minimal surface architectures - traditionally dependent on complex additive manufacturing - can instead emerge directly from the physics of fluid interfaces shaped by programmable boundary conditions. We present a simulation-to-fabrication workflow, that includes a boundary-driven minimal-surface solver integrated in Grasshopper/Rhino, and an experimental system that implements in a neutral buoyancy environment simulating microgravity. This enables the generation of customizable Schwarz-P-inspired with tunable geometry and thickness, illustrating a scalable pathway for material-efficient, on-orbit fabrication. To validate performance in true microgravity, a flight experiment on the International Space Station is scheduled for the first quarter of 2027 and we here detail the additional considerations required for this experiment.
