Self‐folding origami is of great interest in current research on functional materials and structures, but there is still a challenge to develop a simple method to create freestanding, reversible, and complex origami structures. This communication provides a feasible solution to this challenge by developing a method based on the digit light processing technique and desolvation‐induced self‐folding. In this new method, flat polymer sheets can be cured by a light field from a commercial projector with varying intensity, and the self‐folding process is triggered by desolvation in water. Folded origami structures can be recovered once immersed in the swelling medium. The self‐folding process is investigated both experimentally and theoretically. Diverse 3D origami shapes are demonstrated. This method can be used for responsive actuators and the fabrication of 3D electronic devices.
