It's more often a painstaking plod through which the extraordinary gradually becomes ordinary. But we may be at an inflection point along that path when it comes to engineered structures whose mechanical properties are unlike anything seen before in nature, also known as mechanical metamaterials. A team led by researchers at the University of Michigan and the Air Force Research Laboratory (AFRL) has shown how to 3D print intricate tubes that can use their complex structure to stymie vibrations.
