  Kirigami, art of paper cutting, enables two-dimensional sheets transforming
into unique shapes which are also hard to reshape once with prescribed cutting
patterns. Rare kirigami designs manipulate cuts on three-dimensional objects to
compose periodic structures with programmability and/or re-programmability.
Here, we propose a new class of three-dimensional modular kirigami by
introducing cuts on cuboid-shaped objects, based on which constructing two
quasi-three-15 dimensional architected kirigamis with even-flat structural
form. We demonstrate the proposed architected kirigamis are with rich
mobilities triggered by kinematic bifurcations inherited from their composed
modular kirigami, and can undergo living-matter-like metamorphosis evolving
into miscellaneous transformable three-dimensional architectures and even a
pluripotent platform capable of being re-programmed into curvature different
surfaces through inverse design. Such 20 metamorphic structures could find
broad applications in reconfigurable metamaterials, transformable robots and
architectures.
