3D-printed auxetic metamaterials that protect where traditional materials fail. Born from scientific research and validated with real accident data.
Cellmets is a spin-off of Politecnico di Milano and Università di Milano-Bicocca. We combine real-accident analysis, advanced biomechanics and additive manufacturing to design the next generation of energy absorption systems.
Starting with the helmet, we have developed impact-absorption solutions engineered around the real dynamics of trauma, with the concrete goal of improving brain protection: a solution that combines advanced modelling and additive manufacturing to optimise the impact response under realistic conditions.
CELLMETS technology is designed to extend beyond the helmet, with applications in sports protection, occupational safety, and any sector where managing impacts and vibrations is critical.
Manufacturers keep their design, we deliver the innovation that makes the difference where it really matters: in impact absorption.
CELLMETS has developed a proprietary methodology to design metamaterials capable of absorbing mechanical energy (impacts, shocks, vibrations) more efficiently than traditional solutions.
This technology enables 3D-printed modular structures, optimised to respond in a controlled and adaptive way to any load condition, of arbitrary complexity.
In this way, the foam layer can be replaced by metamaterial blocks, fully parameterisable in terms of density and mechanical strength, opening up new frontiers in performance, customisation and design.
Microstructures engineered to absorb loads beyond the reach of conventional foams. The higher the load, the higher the absorption.
Auxetic lattice · 3D printed
Unlike EPS, which shatters on the first impact, our metamaterials tolerate multiple impacts without compromising performance. A crucial property in real accidents, where impacts are rarely isolated.
