Gigantic 3D printer Answered
This 3D printer is a giant step up from other 3D printers. Where most 3D printers make items that you can hold in your hands, this machine by Enrico Dini in Italy is making items you can walk inside. It lays them up tiny layer by tiny layer and the result is pretty sturdy. One day it might even be used on site to make intricate buildings.
