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 ...

Are you fond of drawing some random doodles? Have you ever imagined some magic tricks that would transform your boring 2D picture into a realistic 3D model? Well then, turning a 2D shape into a 3D ...

Researchers developed an algorithm that can align two 3D shapes by mapping their volumes, which is more effective than other methods that align shapes by only mapping their surfaces. In computer ...

Researchers have developed a method to change the shape of a flat sheet of elastomer, using actuation that is fast, reversible, controllable by an applied voltage, and reconfigurable to different ...

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 ...

A strange shape described by mathematician Lord Kelvin in 1871 and predicted to behave unusually in a fluid has finally been fully studied in the real world thanks to 3D printing – and it seems Kelvin ...
