BigRep has developed a 3D printed electric motorcycle in which all of the motorcycle’s components are 3D printed except for its motor and battery. Named, NERA, the compact e-bike has the dimensions of 190cm x 90cm x 55cm and possesses a bionic passenger seat, making it the first fully 3D printed motorcycle that is functional in the world.
The motorcycle’s prototype which was designed by NOWlab, BigRep’s innovation consultancy, was printed on BigRep’s large-scale 3D printers. And it illustrates the numerous benefits that 3D printing offers for the production of end-use parts, especially in the case of batch sizes that are between lot size one to small series, by reducing lead times and costs, optimising supply chains and limiting dependency on supplier networks.
In building NERA, engineers did not just adapt existing motorcycle designs, but instead envisioned a bike for large-format FFF technology, setting a benchmark for truly creative design and breaking the limits of traditional mechanical engineering. Among the many innovations featured in NERA are the airless tires with a customised tread, a lightweight rhomboid wheel rim, as well as flexible bumpers instead of the conventional bumpers, and an electric engine, which is fitted in a customisable case.
Daniel Büning, Co‐Founder and Managing Director of NOWlab has said, “The NERA combines several innovations developed by NOWlab, such as the airless tire, functional integration and embedded sensor technology. This bike and our other prototypes push the limits of engineering creativity and will reshape AM technology as we know it.”
