A prism is a 3D shape which has a constant cross section - both ends of the solid are the same shape and anywhere you cut parallel to these ends will give you the same shape. For example, in the prism ...

Researchers at the Institute of Science Tokyo have developed a neural-network-based 3D imaging technique that can precisely ...

Computer-aided design (CAD) is the go-to method for designing most of today's physical products. Engineers use CAD to turn 2D ...

In the early 17th century, Galileo was demonstrating telescopes, and Johannes Kepler was experimenting with new 3D shapes. Over the subsequent 400 years, many advances have been made in astronomy. But ...

It may seem distinctly low-tech compared to some of the many technology trends I write about, but 3D and 4D printing will have very wide applications – and could be particularly powerful when combined ...

Inside the Silicon Valley factory of a startup called Sakuu, a new type of 3D printer is reinventing how batteries are made. The technique, which prints using thin layers of powder, can change what ...

Flat-pack furniture is commonplace, and flat-pack pasta might be one day too. Wen Wang of Carnegie Mellon University in Pennsylvania and her colleagues have developed edible 2D pasta that swells into ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Some examples of solids that incorporate 2D shapes are mentioned in this video by Sanchit — for example ...
