NERA: World’s First Fully 3D Printed E-Bike Leave a comment

The NERA e-motorcycle started with an idea: create a functional prototype that revolutionizes mobility and can be produced entirely with 3D printing. NERA is fully 3D printed, only 15 parts.


With Marco Mattia Cristofori in the design lead at BigRep, NERA e-Bike was engineered from the ground up, disrupting traditional design, engineering and production in every aspect. The result is a 100-percent, customizable, functional prototype, designed and produced with more time- and cost- efficiency than previously imaginable.


In building NERA, BigRep’s designers and engineers envisioned a bike designed for large-format FFF technology. Prototyping for standard manufacturing methods has extremely limited design possibilities when it comes to mechanical functions, as well as to the design language of objects. For further information see the IDTechEx report on 3D Printed Materials Market 2020-2030: COVID Edition.


First the team arranged the functionally relevant core parts, then design the outer shell. The battery, motor, cable and control systems are not printed. The motor is electric since traditional combustion engines cannot be embedded in polymer objects. The electronics can be adjusted individually and are integrated as a modular system that allows individual settings.
