For
achieving active shape transformable materials and structures,
smart materials with shape memory effects along with deliberate structure
design are generally used as the critical parameters in realizing
structure transformation. Beyond such conventional approaches, here
a novel structure-guided multimaterial three-dimensional (3D) printing
strategy based on twistable origami structures is demonstrated to
realize dynamic smart shape transformation. By thermally or photothermally
triggering the prestored energy in the twisted structures, the 3D-printed
integrated origami structures based on Miura and square-twist origami
structures coupled with modifying by kirigami approaches are enabled
to present a variable multistep transformable feature as well as a
manipulatable stimulus-response behavior. Such shape transformation
configuration allows the integrated origami and kirigami structures
for constructing smart structures in delivering dynamic multifunction.
More importantly, the shape transformation mechanism also suggests
a unique capability in mechanical energy storage and release, promising
a novel prototype of mechanical actuators. Implication of the results
offers a great platform to construct smart and active structures using
structure-guided strategies.
