About
Chang-Geun Chae is pioneering the emerging field of sustainable 4D printing, where printed objects transform over time in response to environmental stimuli. His core research focuses on developing multi-stimuli-responsive sulfur-rich polymer composites—materials derived from waste elemental sulfur that can be programmed to change shape autonomously. Chae’s major contribution lies in overcoming the fundamental challenge of 3D printing crosslinked polymer networks, enabling the fabrication of complex geometries for soft robotics and smart systems. His 2025 paper on closed-loop 4D printing has already garnered 7 citations, demonstrating immediate impact in this nascent field. Notably, his work introduces a modular assembly approach for multi-functional smart parts, advancing the practical application of these sustainable materials. By repurposing industrial sulfur waste into high-value, shape-programmable composites, Chae is addressing both environmental sustainability and the technical demands of next-generation autonomous devices. His research sits at the intersection of materials science, additive manufacturing, and soft robotics, offering a pathway toward truly recyclable, intelligent materials that can execute complex tasks without external control.
