Three-dimensional printing may sound like stuff from a sci-fi movie, but so did airplanes and cars when they were first mentioned in history. Today, 3D printers are as widespread as those cars (with bicycle wheels) of old, but they are, in fact, real and are not mere specks from a Harry Potter world.
3D printing technology, in general, works like traditional printers. A typical 3D printer spits out thin lines of plastic or other material, one layer on top of another, and in the process, creating a physical, three-dimensional object.
Most of today’s 3D printers are found in commercial settings, which is quite logical. After all, they cost thousands of dollars. Not for long, though. As some major printer vendors are increasingly showing interest in the technology.
Hewlett-Packard, for one, is partnering with smaller company Stratasys to sell commercial 3D printers. Soon, other manufacturers are expected to follow suit.
