| summary |
Architects working on complex building geometries continually seek innovative processes to allow for feasible and cost-effective construction. The mass customization of double curved building façade panels has been specifically challenging regarding surface continuity, panel accuracy and waste reduction. With advanced digital design and fabrication tools, architectural firms such as ZHA, Gehry Technologies, and Atelier Jean Nouvel have been pushing the limits to achieve enhanced building envelope manufacturing solutions. Current research in materially-informed design-to-robotic production (D2RP) explores the impact of robotic fabrication on enhancing production practices. Several panel manufacturing methods have been proposed such as stretch bending, die forming, hydroforming, single and multipoint forming, the most successful being hybrid methods like multipoint stretch forming. In developing countries, the challenge of utilizing such materials and tools is amplified. In this paper, we introduce a method that couples the non-planar robotic deposition of clay as a material characterized by its longevity, reduced heat transfer, low cost, low maintenance lightweight and local abundance, with multipoint forming to optimize the manufacturing of double curved façade panels in hot arid climates. A 6-axis robotic arm was used to produce multiple functionally double-curved panels by depositing clay in a non-planar fashion and normal to the surface of a multipoint forming machine that was designed and manufactured using 3D printed movable actuators to create adaptive molds. A workflow was developed using Grasshopper for develop a streamlined coupling between the rapid code for the robotic simulation and depositing, and the multipoint forming synchronized actuator movement per clay panel, based on a given full building façade geometry. The resulting double-curved facade panels were optimized structurally, materially, and spatially, and were shown to significantly reduce material waste with low environmental impact and accelerated rate of double-curved panel production. |
