Origami/Kirigami for Shellular Fabrication

Description

Shellular Funicular Structures (SFSs) are single-layer,two-manifold structures with anticlastic curvature, designed in the context of graphic statics. They are considered efficient structures applicable to many functions on different scales. Although their geometry is quite complex, they consist of planar faces that facilitate their fabrication. This research introduces a computational algorithm for translating a Cellular Funicular Structure (CFS) to a Shellular Funicular Structure (SFS) and explores a fabrication method using the origami/kirigami technique. Building the structure out of a flat sheet of material will reduce the construction costs and wastes and extend the use of the systems to large scales.
