A new 3D printer uses light to transform gooey liquids into complex solid objects in only a matter of minutes. The printer can create objects that are smoother, more flexible and more complex than ...

How to describe 3D shapes 3D shapes are described by their faces, edges and vertices. The faces can be the same shape or different, and a 3D shape could have a curved surface as well as flat faces.

The MIT team's 3D printer emits a reconfigurable beam of light into resin to create solid shapes.

One active area of research and development is "self-actuating" objects: flat materials that transform themselves through material forces into the desired 3D object.

The popularity of 3D printing has been increasing dramatically while the prices for such printers have been rapidly decreasing. In addition to toys and gadgets, real-world practical uses include a ...

Students could be presented with a collection of objects and asked to write down as many descriptions for the position of various objects as possible. For example, the box is behind the teddy and ...

Carbon3D shows off a fascinating liquid-resin process that bypasses the typical layering approach of 3D printing.

We continue our 3D printing discovery series by showing you how quick and easy it is to customize the size of pre-designed objects -- without ever going into a 3D design program.

We continue our DIY-IT discovery series on 3D printing by exploring how to download and print 3D objects from the Internet. If you can download a file, and you have a little patience, you can do this.
