abstract⁄This paper presents an innovative approach to the design and fabrication of threedimensional objects from singlepiece flat sheets, inspired by the origami technique of twistclosing. While in origami twistclosing is merely used to stabilize a cylindrical or spherical structure, ensuring it maintains its shape, this research investigates the potential of twistclosing as a multifunctional mechanism that also activates and controls the transformation of a planar surface into a predesigned threedimensional form. This exploration is directed towards an intended application to stiff and brittle sheet materials that are difficult to shape through other processes. The methods we have developed draw mainly upon principles of lattice kirigami and laminar reciprocal structures. These are reflected in a workflow that integrates digital formgeneration and fabricationrationalization techniques to reference and apply these principles at every stage. Significant capabilities of the developed methodology include 1 achievement of pseudodoublecurvature with brittle, stiff sheet materials 2 stabilization in a 3D endstate as a frameless selfcontained singleelement laminar reciprocal structureessentially a compliant mechanism and 3 an ability to preencode 3D assembly constraints in a 2D cutout pattern, which guides a moldless fabrication process. The paper reviews the precedent geometric techniques and principles that comprise this method of 3D surface fabrication and describes a sample deployment of the method as applied to the design of laminar modules made of highpressure laminate HPL.
