Carbon3D's technology does this by harnessing oxygen and light to grow the parts continuously as the object rises like the T-1000 from Terminator out of the resin. One experiment captured in a study published Monday in Science shows a mini-Eiffel Tower emerging from a vat of blue liquid in just six minutes.
