3D Printing blog Fabbaloo says the general public has just recently learned about 3D printing and thus simultaneously overestimates and underestimates what can be done.
While a personal 3D printer that can print anything is still mythical and will be for quite a while, 3D printing has already been used for things the public is barely aware of.
This is a technology that’s been around for decades. 3D printed food experiments have taken place for at least five years. It has been used to prototype many of the things around your house. It’s in airplanes you fly in. It’s even in your mouth if you happen to use Invisalign braces!
