There’s no questioning that 3D printers are the wave of the future. They allow small-time (and soon to be big-time) manufacturers the ability to literally “print” whatever model they can create digitally on their computers. You can learn more about the process here but what’s important is how people are using the technology. Sure, the printers can be used for good (like the creation of prosthetic limbs) but how about when some of the stranger hobbyists get their hands on them? You get gamers creating some of the coolest Christmas gifts ever. Check out some of the coolest uses for the technology below.
