Will 3D printing take off?Will 3D printing take off?

3D printing is a way of making real objects from designs on a computer.

Rather than making something by sticking lots of small parts together, a 3D printer can build complicated items in one piece.

It's been used in the manufacturing industry for quite some time, but as the technology improves the possibilities increase.

3D printers are slowly becoming cheap enough for people to have a small one at home.
