Da Vinci AiO 3-D scanner-printer, $800
31 of 36
The all-in-one scanner and printer, made by XYZprinting, lets you 3-D print objects without knowing how to design anything. You can just put an object inside, and a couple hours later, you'll have a plastic replica of that object. In theory anyway -- In reality, the Da Vinci AiO totally failed to copy basic objects. But it's an amazing concept that shows the potential for 3-D printing in the future.
