Renault Group and the French Alternative Energies and Atomic Energy Commission (CEA) have jointly developed a novel materials architecture that combines disruptive digital design with additive manufacturing (3D printing). This innovation enables the creation of components with exceptional properties, featuring adaptive and customizable behavior.

The core of the advancement lies in a unique lattice structure designed computationally and produced via 3D printing. This approach allows for precise control over material properties, such as stiffness and damping, in ways impossible with conventional materials and manufacturing.

The most immediate and promising application area is automotive interior comfort. The technology could lead to next-generation seat components, armrests, or headrests that dynamically adapt their shape and firmness to individual passengers, enhancing personalized comfort. Beyond seating, potential uses extend to other structural or damping elements within the vehicle cabin.

This collaboration continues a long-standing partnership between Renault and the CEA focused on advanced research for future mobility, positioning computational design and additive manufacturing as key enablers for next-generation automotive components.

​Renault Group et le CEA ont développé une architecture de matériaux inédite, qui allie conception numérique de rupture et fabrication additive (impression 3D). Cette innovation pourrait permettre de concevoir des éléments aux propriétés exceptionnelles, et au comportement adaptatif et personnalisable. Les potentiels d’applications à l’automobile sont prometteurs, avec en premier lieu le confort à bord.
