New Self-Healing Polymers Could Make 3D Printed Parts Last Longer
By Quantum Server Networks — November 2025 In a remarkable step toward smarter and more sustainable additive manufacturing, researchers at the Rochester Institute of Technology (RIT) have developed a new class of self-healing photopolymers that could dramatically extend the lifespan of 3D-printed parts. Led by Professor Christopher Lewis from RIT’s College of Engineering Technology, the research introduces a novel way for printed materials to automatically repair cracks and deformation — bringing 3D printing a step closer to mimicking the resilience of biological systems. The work, supported by the U.S. Department of Defense and conducted in partnership with RIT’s AMPrint Center , focuses on designing stimuli-responsive photopolymers that react to light exposure by self-repairing internal damage. The results, reported by 3D Printing Industry , highlight a transformative direction in materials science — one that merges chemistry, engineering, and biomimicry to give printed c...
