Although 3D printing has just picked up, there are quite a few 3D printed bicycle designs out there. None, however, are made of steel. None of them also look as beautiful as the Arc Bike. Created by the students at TU Delft, based in The Netherlands, the Arc bike has an intricately detailed bike frame made to look like it was woven, rather than printed. You really need to watch the video below to see what goes into creating this work of art, or should I say work of Arc! Designer: Arc Bicycle Team (TU Delft)
