| Abstract Scope |
Responsive feedstocks for additive manufacturing have opened a new regime of material design, where printed materials can morph into programmed architectures with exposure from a specific stimulus. Shape memory polymers have shown success in printability and in programmability with heating and mechanical force but is generally limited in a one-way shape morphing. Liquid crystal elastomers (LCEs) have more recently been developed for additive manufacturing where programming can be instated during the printing of complex shapes and shape morphing can occur reversibly and repeatably over many cycles of stimuli exposure. Here, we report custom LCE direct ink write feedstocks that can be programmed during printing and reprogrammed with localized light and reversibly locking stimuli to induce novel behaviors like locomotion and reversibly locking stiffness change. |
