Form-Finding to Fabrication: A Parametric Shell Structure Fabricated Using an Industrial Robotic Arm with a Hot-Wire End-Effector

The increasing application of computer technologies in architecture has facilitated interactive collaboration between form-finding and realization. In contrast to conventional methods, various form-finding processes embedded in digital media have recently been investigated. Robotic technologies have also been utilized to execute hazardous tasks and to perform more challenging and complex fabrication in architecture. In this study, we experiment with form-finding and robotic fabrication to explore innovative design possibilities. After selecting a particular site, we determine a rigorous geometric form for construction. Structural analysis of the design is performed to verify the stress distribution and failure mechanisms. The design employs an industrial robotic arm with a hot-wire end-effector to determine an optimum method for full-scale assembly and on-site installation of the design. Finally, this study accurately verifies the constructability of the designed form and evaluated the challenges and opportunities associated with the process. The findings demonstrate that this approach complements the potential impacts of the design process, practice, and aesthetics.
