Robotic Incremental Sheet Forming | CITA Studio Workshop | 2020

The workshop is centered around the application of Robotic Incremental Sheet Forming (RISF) as a fundamental approach for the exploration of materials and structures. RISF functions as a fabrication technique to mold initially flat, slender metal sheets into three-dimensional configurations. This procedure entails the traversal of a ball-head tool across the metal surface, inducing localized plastic deformation. Viewed from an architectural perspective, RISF presents an intriguing aspect owing to its capacity to obviate the necessity for intricate and costly molds, as it directly shapes finished metal components. This attribute renders RISF exceptionally well-suited for the production of diverse and customized outputs, a realm where metalworking expenses would otherwise be excessively high. The ongoing trajectory of research at CITA delves into the optimization of RISF's efficacy, thereby facilitating the generation of lightweight and slim architectural structures. 

The workshop involves an examination of the thematic concentration for the semester, which pertains to heterogeneity. This exploration is conducted through the design investigation of material heterogeneities, encompassing those that are inherent, induced, and assembled. The focal point is primarily directed towards the various length scales encompassing materials, elements, and assemblies. Concurrently, the temporal dimensions of pre-fabrication, intra-fabrication, and post-fabrication are given significant attention. The amalgamation of these contemplations is synthesized within the proposition, manufacturing, and assembly phases of an architectural structure. 

Our team aims to construct the metal stool by fastening multi-metal sheets to strengthen the stool structure.
