“…The first involves using thin shell elements, which approximate through bending the boundary geometry representation of a polyhedral frame. In [5,6], developable thin sheets are used as structural shells to build polyhedra through curved folding. In MycoTree [7], a segmented structure is built with struts and nodes of mycelium grown into moulds made of developable plastic sheets.…”

“…These methods referred to original studies from the nineteenth century when the reciprocal relationship between form and force diagrams for 3D polyhedral structures was discovered [3,4]. Because of the difficulties involved in working with such three-dimensional diagrams, their use has not been fully exploited until recently, when a number of experimental polyhedral structures were realised [5][6][7][8][9][10]. These examples indicate that polyhedral structures can be used for various applications, delivering structural efficiency and intrinsic elegance.…”

Polyhedral structures are a fascinating and efficient case of structural virtuosity. However, their adoption to date has been limited because of geometrical, structural and fabrication complexities. This paper introduces a modelling pipeline to provide a rigorous -yet practical-approach to the challenges linked to the realisation of 3D polyhedral structures, from early-stage design to fabrication. A custom-developed modelling add-on is utilised for reconstructing the underlying topology of 3D polyhedral structures and implementing a component-based approach for the design development. Concurrently, an innovative digital fabrication strategy based on Additive Formwork Manufacturing is presented, with a detailed description of the process and illustration of a fully-functional physical prototype. Methodological and software developments are applied to the fabrication experiments where the approach is tested with in-depth design and construction insights. The approach is ultimately discussed for the development of real-world structures and in light of the potential adoption by non-expert computational designers.
