Arc 3D-Printed Bicycle

Designed and built by a group of four Dutch college students as part of a three-month research project, the Arc 3D-Printed Bicycle is a great example of the technology's potential. The students partnered with Amsterdam-based MX3D to utilize their printing process, which uses articulated robot arms to print structures in mid-air, thus allowing for far larger objects to be made than with a traditional printer. While the spider-like frame of the bike could bring weight savings in the future, the current prototype weighs roughly the same as a normal bike, with a fixed gear configuration and off-the-shelf fork, handlebars, and seat.
