4D printing is real, happening now, and has the potential to shape the world. Self-assembly in 4D printing uses materials responding to external stimuli. A regular 3D printer can be used to create 4D ...

Gutenberg’s printing press revolutionized the way the written word was replicated, bringing two-dimensional printing into the world and so vastly increasing accessibility of information. From that ...

Have you ever imaged high-resolution 3D structures at the micro/nanoscale that react dynamically to their surroundings? The 4D printing technology is changing the game by using smart materials that ...

Researchers have developed a way to fabricate a new type of wing that can change its shape in flight for unmanned aerial vehicles (UAVs) cheaply and efficiently using a novel 4D-printing process, they ...
