M EDAG is showing the concept car EDAG Light Car Cocoon the Geneva Salon 2015 how the ultimate lightweight construction of the future could look. Bionic chassis structures created by a 3D printer covered with a fabric skin.

Lightweight construction made visible

On board with this visionary concept is the outdoor specialist Jack Wolfskin, who protects the cocoon from the weather with its outdoor textiles. The fact that the body skin weighs only 19g /m² meets the maximum lightweight construction requirements. This saves a lot of weight and makes the vehicle structure transparent. As a special feature, the outer skin is illuminated from the inside with LEDs. As a result, the compact sports car study not only shines with maximum weight optimization, but also shows a completely new dimension in vehicle design.

In terms of production methods, the Cocoon should also provide an outlook on future technologies. In the 3D printing process, complex structures are produced without tools and in one process, which gives developers unimagined degrees of freedom. Even if the production of structure-relevant components for EDAG is not yet foreseeable in the medium term, the first application cases such as. e.g. Moved within reach in the interior area.
