Two-dimensional (2D) shapes are completely flat. They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they ...

The net of a 3D shape is what it looks like if it is opened out flat. There are many types of nets for the different 3D shapes. A net is made from polygons that can be folded and joined to make a ...

Forget your regular ol’ 3D printer. Why not try using sound waves to form a 3D object? That’s exactly what researchers in Germany set out to do, making use of “acoustic holograms” to form distinct 3D ...

Using a computer and modern software can be a chore to begin with for the visually impaired, but fundamentally visual tasks like 3D design are even harder. This Stanford team is working on a way to ...

A computational design tool created by researchers at Carnegie Mellon and the Swiss Federal Institute of Technology lets you fold a piece of metal or plastic into a “complex 3D shape” like a mask or ...

Three-dimensional printing has been used to create all sorts of things, from car parts and experimental rocket engines to entire houses. Now scientists at MIT have found a way to 3D print objects that ...
