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 ...

Three-dimensional printing, also known as additive manufacturing, takes a digital blueprint and turns it into a physical object using computer-aided design (CAD). A repeating 2D structure is built up, ...

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 ...

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 ...

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 ...
