About

Dr. Zhong Xun Khoo is a pioneering researcher at the forefront of additive manufacturing and smart materials, best known for his foundational work in 4D printing—the evolution of 3D printing where printed objects can transform over time in response to external stimuli. His landmark 2015 review, "3D printing of smart materials: A review on recent progresses in 4D printing," has amassed over 889 citations, establishing it as a seminal reference in the field. In this work, Khoo systematically mapped the integration of shape-memory polymers, hydrogels, and other stimuli-responsive materials into additive manufacturing processes, effectively defining the research agenda for a generation of engineers and materials scientists. Beyond this cornerstone contribution, his research spans the design of programmable matter, bio-inspired fabrication, and multi-material printing techniques that enable unprecedented control over material behavior. Khoo’s work has not only accelerated the development of self-assembling structures and adaptive devices but also inspired applications in aerospace, biomedical devices, and soft robotics. His ability to bridge fundamental materials science with practical engineering challenges marks him as a key architect of the next manufacturing revolution.
