TL;DR: The markedly simplified creation of high-resolution complex 3D reprogrammable structures promises to enable myriad applications across domains, including medical technology, aerospace, and consumer products, and even suggests a new paradigm in product design, where components are simultaneously designed to inhabit multiple configurations during service.

TL;DR: A theoretical model is developed to predict the deformation behavior of active composites that can take multiple shapes, depending on the environmental temperature, and has a great potential in 4D printing applications.

TL;DR: This work demonstrates a new reversible shape-changing component design concept enabled by 3D printing two stimuli responsive polymers—shape memory polymers and hydrogels—in prescribed 3D architectures and develops 3D nonlinear finite element models to help understand the interplay of geometric, material, and environmental stimuli parameters.

TL;DR: The g-DLP method is presented, showing the direct fabrication of complex 2D/3D lattices with controlled buckling and deformation sequence, negative Poisson’s ratio metamaterial, presurgical models with stiffness variations, composites for 4D printing, and anti-counterfeiting 3D printing.
