We’ve seen 3D printed bikes before. Normally they’re badass. Normally, they look pretty much just like every other bike. The Arc Bicycle though, featuring a 3D-printed steel frame, is anything but normal.
Created by a team of five students at the Technical University of Delft in the Netherlands, the Arc features an entire bicycle frame that was printed with steel, a world first, and what’s more – they’ve used an open mesh frame rather than traditional tubes.
Every wire of the steel frame was built up one millimetre at a time by a robot, which welded each tiny piece of steel on to each wire until the final frame was complete. It only took 100 hours. Lucky the robot didn’t have any pre-arranged dinner plans.
