| Abstract |
This study develops a fully integrated digital to physical workflow for architectural form generation, simulation, and fabrication, emphasizing
computational precision and robotic execution. The process begins with Circle Packing algorithms implemented in Grasshopper to generate
conoidal geometries optimized for surface continuity and material efficiency. Iterative daylight simulations were conducted to refine
performance with respect to solar penetration and shading, while VR simulations validated spatial legibility and perceptual quality prior to
fabrication. For production, an industrial six-axis robotic arm equipped with a hot-wire cutter was deployed to mill expanded polystyrene
blocks into large-scale components with high precision. After calibrating and fine-tuning of the hot-wire cutting tool, Robotic toolpath
strategies were optimized to reduce material waste and ensure geometric fidelity. The prefabricated units were subsequently assembled on site,
achieving structural coherence and fabrication precision. Overall, the study demonstrates the feasibility of a tightly coupled workflow in which
parametric design, environmental analysis, and robotic fabrication converge into a continuous design-to-construction pipeline. |
