Aus researcher 3D-prints design to protect buildings from impact damage

A researcher from Queensland University of Technology has 3D-printed a product design that could help protect buildings from collision damage and high impact forces, equivalent to a car travelling at 60km/hr. It's inspired from a material used in running shoes and memory foam pillows. The researcher used off-the-shelf bioplastic to 3D print geometric shapes that mimic auxetic materials' behaviour.
