German engineering firm Edag developed a concept car with a fully bionically optimised, additively manufactured (3D-printed) vehicle structure. The ‘Light Cocoon’ focuses on lightweight construction and to this end takes inspiration from nature. The concept features an organic-looking, lattice-like passenger cage covered with a weatherproof textile outer skin panel, produced by outdoor specialists Jack Wolfskin.

LED lighting technology installed behind the outer skin panel makes the vehicle's skeleton-like structure visible. The color of the outer skin can be changed at will, according to the driver’s taste. Despite the fact that material has only been used in areas where it was necessary for function, safety and stiffness, all requirements imposed on structurally relevant components are met.
