3D printing is the wave of the future.

Whether it's a plastic iPhone tripod, a metal airplane component, or real transplantable human organs, 3D printing can make it all. If that's not cool enough, the process also reduces waste and improves customizability and will someday soon be very cost efficient.

The process is just like the laser printers you've got at home, but replaces the ink with things like nylon, plastics, and metals. Designs are drawn up on a computer and sent to the printer as usual, but instead of placing one layer of ink onto paper it builds layer after layer of material into a three dimensional object. Printers would generally be built like this:
