About

Kah Fai Leong is a pioneering figure in the field of additive manufacturing, with a particular focus on 3D and 4D printing of smart materials. His landmark 2015 review, "3D printing of smart materials: A review on recent progresses in 4D printing," has amassed over 889 citations, underscoring its profound influence on the research community. In this work, Leong systematically explored the integration of stimuli-responsive materials into additive manufacturing, laying the groundwork for the emerging field of 4D printing—where printed objects can change shape or function over time in response to environmental triggers. Beyond this seminal review, his broader contributions span process optimization, material development, and the application of rapid prototyping technologies across engineering and biomedical domains. Leong’s research has not only advanced the fundamental understanding of additive manufacturing but also inspired a generation of scientists and engineers to push the boundaries of what is possible with programmable materials. His work remains a cornerstone for anyone exploring the intersection of materials science and digital fabrication.
