(Nanowerk Spotlight) Compared to creating static objects with 3D printing, 4D printing systems add time as the fourth dimension to 3D printing: 4D printing allows a 3D printed structure to change its ...

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, ...

(Nanowerk Spotlight) The colors in the world around us are produced through either absorption of light by molecules (pigmentary colors) or scattering of light by nanostructures (structural colors).

3D printing, also called additive manufacturing, is rapidly becoming commonplace in all industries, including aerospace, automotive, medical and dental, and consumer and industrial goods. Some ...

A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to ...

If you’re a fan of the Big Bang Theory, you may remember how Howard and Raj spent three hours printing a 25 cent whistle in a 3D printer. More of a sci-fi fan? Then, you likely watched in Jurassic ...

A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to ...

Specific nerves may be stimulated artificially, for example to treat pain. The finer the nerves, the more difficult it is to attach the required electrodes. Researchers at the Technical University of ...

Whilst 3D printing continues to grow in popularity, some scientists are already looking at the next step – how to make their objects transform from one shape to another using 4D printing. Essentially, ...

If you thought 3D printing was confusing, just wait until four-dimensional printing hits. The somewhat erroneously named term has come into vogue as of late with a few MIT-driven projects that promise ...
