The world's first 3D-printed car is crude by design, its dashboard looking like stacked silicone beads from a caulking gun. Its flanks, meanwhile, are smooth, resembling the exposed parts of the BMW i3's matte carbon tub. "We milled the sides to show how that would look," Rogers says. "Some of the other parts are just how they came out of the printer, so you can see that. But we can make it look however we want. You could put a vinyl wrap on it and the car would still be completely recyclable."
