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, ...

A research team out of Korea has built a 4D printer that uses recycled materials to make soft robots — robots made of non-rigid materials. Elemental sulfur, a byproduct of petroleum refining, is ...

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 ...

4D printing, a new technology that creates parts that change shape when exposed to stimuli like heat or moisture, could be vulnerable to hackers that infect printers and manipulate parts in malicious ...

The first time I wrote about MIT's Skylar Tibbits and what he calls 4D printing, I refused to use that term. It seemed pretentious and, well, dishonest. Self-assembly meets 3D printing was more ...
