Project Overview

Paper is a lightweight, abundant, and bio-degradable material. In addition, paper affords rich physical interactions including folding, printing, and painting on its surface. We present the design and exploration of a new electrical and reversible paper actuator printed by a FDM 3D printer. The actuator is composed of inexpensive materials, such as common paper and off-the-shelf thermoplastic printing filaments. The fabrication process is fast and straightforward, which requires a single layer printing with a desktop FDM printer. Our paper actuator can be easily embedded into everyday objects to enable new types of paper-based shape-changing interfaces that exhibit motion, transformation, and rich interactivities such as pop-up books, toys, origami robots, and lampshades.
