N2 - This paper describes a novel method to fabricate three-dimensional (3D) structures composed of a stimuli-responsive hydrogel. Using this method, 3D structures with internal gaps (ex. framed structure, hangout structure etc.) can be printed directly in supporting viscous liquid and polymerized with ultraviolet (UV) irradiation. We confirmed that the fabricated 3D microstructures with internal gaps successfully changed their shapes by external stimuli such as temperature. Our proposed method would be an effective tool for creating hydrogel 3D microstructures with various types of stimuli (optical, pH, molecular, etc.), for applications in soft actuators/robotics, and self-assembly/adaptive systems.
