Soft matter elements undergoing programed, reversible shape change can contribute to fundamental advance in areas such as optics, medicine, microfluidics, and robotics. Crosslinked liquid crystalline polymers have demonstrated huge potential to implement soft responsive elements; however, the complexity and size of the actuators are limited by the current dominant thin‐film geometry processing toolbox. Using 3D printing, stimuli‐responsive liquid crystalline elastomeric structures are created here. The printing process prescribes a reversible shape‐morphing behavior, offering a new paradigm for active polymer system preparation. The additive character of this technology also leads to unprecedented geometries, complex functions, and sizes beyond those of typical thin‐films. The fundamental concepts and devices presented therefore overcome the current limitations of actuation energy available from thin‐films, thereby narrowing the gap between materials and practical applications.

具有软机器人功能的4D打印执行器

进行程序化，可逆形状更改的软物质元素可以在光学，医学，微流体学和机器人学等领域取得根本性的进步。交联的液晶聚合物已显示出实现软响应元件的巨大潜力。但是，执行器的复杂性和尺寸受到当前主流的薄膜几何处理工具箱的限制。使用3D打印，可在此处创建刺激响应型液晶弹性体结构。印刷过程规定了可逆的形状变形行为，为活性聚合物系统的制备提供了新的范例。这项技术的累加特性还导致了前所未有的几何形状，复杂的功能和超出了典型薄膜的尺寸。
