We developed an inverse design method for constructing 3D reconfigurable architected structures — we synthesized modular origami structures whose unit cells can be volumetrically mapped into a prescribed 3D curvilinear shape followed by volumetric shrinkage for constructing modules. After modification of tubular geometry, we searched modular origamis’ geometry and topology for target mobility using a topological reconstruction of modules. Our inverse design by the geometric and topological reconstructions can provide an effective solution to constructing 3D curvilinear reconfigurable structures with multi-degree-of-freedom.
