3D printers are far from a perfect technology at this point, but one of their most glaring issues is that their printing capacity is limited to the size of the machines. The print head on a 3D printer can only travel so far, which is why moving it onto a wheeled platform that’s completely mobile is a brilliant idea, and could be quite a leap for the technology. The 3&Dbot, developed by a bunch of industrial designers at NEXT and LIFE, still needs a flat surface to work on, but the size of a part or object it can create is almost limitless—with a large enough area to work. There are some unique challenges to making a mobile 3D printer like this work, though, most important being the development of tracking systems that ensure its movements are precise enough to accurately recreate a 3D model. And that includes controlling the omni-directional wheels that give the attached printhead unlimited degrees of motion.
