3D Printing sounds like something out of a science fiction book. But the reality is, it's already here. It's basically a form of manufacturing where layers of material are added together to create the desired product. A lot of this manufacturing is done with lasers, some of the products are made with polymers, some are made with powders. The most important aspects of these different methods are speed, cost and quality. As a result, 3D printing has lots of different applications.

In the health field, organs and body parts could be built using this new technology. Cells are deposited onto a gel medium and subsequently built up in layers. The result is the bones can literally be built intact, without the need for polishing or refinement. Molding will become obsolete, which will save lots of money and time, as well as the condition of the original. Dentistry will also benefit hugely from 3D printing....
