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: In this article, the authors present a new paradigm to fully recycle epoxy-based carbon fiber reinforced polymer (CFRP) composites, where the epoxy matrix can be dissolved as the EG molecules participate in bond exchange reactions (BERs) within the covalent adaptable network (CAN), effectively breaking the long polymer chains into small segments.

TL;DR: In this article, a new thermosetting vitrimer epoxy ink and a 3D printing method that can 3D print epoxy into parts with complicated 3D geometries, which later can be recycled into a new ink for the next round of printing.

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.
