About

Koen Clays is a pioneering researcher whose work bridges the frontiers of photopolymerization and advanced materials engineering. His key research areas include 3D printing, functionally graded materials (FGMs), and photochemistry, with a particular focus on grayscale photopolymerization—a technique that enables precise spatial control over material properties. Clays’ major contribution lies in demonstrating how grayscale light patterns can create FGMs with tailored mechanical, thermal, and swelling gradients in a single print, eliminating the need for multi-step processes. This innovation has profound implications for biomedical implants, microfluidics, and soft robotics, where property gradients are essential. His most-cited paper, "From Grayscale Photopolymerization 3D Printing to Functionally Graded Materials" (2024), has already garnered 27 citations, reflecting its rapid impact. Clays’ work, often in collaboration with leading researchers like Rob Ameloot, has been featured in high-impact journals such as *Advanced Functional Materials*. By transforming 3D printing from a structural to a functional technology, Clays is shaping the future of additive manufacturing, making it more versatile and applicable to real-world challenges.
