New 4D Printed Composite Material is Capable of Complex Movements

By using additive manufacturing technology, researchers at the University of Pittsburgh’s Swanson School of Engineering and Clemson University have developed a new hybrid material that is capable of moving independently when exposed to heat or light. What makes this 4D printed material unique is the ability to control the amount of heat and light exposure to create complex movements and transformations. The material was made by combining photo-responsive fibers with thermo-responsive gels that not only interact with each other but will independently react to either heat or light. The material is well-suited to the development of assistive devices that can adapt and display distinct behavior based on exposure to specific environments.
