Hybrid 3D Printing Pick and Place Robotics for Additive Fabrication of 4D Composites
Abstract
4D printing, as a novel extension of additive manufacturing, has seen significant progress since its birth five years ago. However, 4D printing also faces some significant challenges, including relatively low structural stiffness, low actuation forces, and slow actuation speeds. The objectives of this proposed research are to address these challenges by developing fundamental knowledge of using a multimaterial approach to design actuators with large actuation forces to trigger snapping of 3D printed multimaterial structures for rapid responses and by establishing a transformative paradigm of an “additive approach” where 3D printing is used to create complex geometries and robotic pick and place (PnP) is used to “add” reinforcing components. Through this combinatory approach, 4D printed structures with high overall stiffness, large and rapid on demand shape changes, and large payload carrying capabilities can be achieved.
