3D-Printed Surfaces Inspired by Nature

Interesting idea, biomimicry directly linked to 3D Printing, then back to human needs.  How deep can this go? 

 3D-Printed Surfaces Inspired by Nature

Scientists at Germany's Ruhr-Universität Bochum and Kiel University three-dimensionally (3D)-printed surfaces that mimic the color of blue Morpho butterflies via two-photon polymerization (2PP). The 2PP laser-based printing technology allows 3D processing of photosensitive resins, enabling the generation of complex structures from virtual computer models without the need for support structures. The technology also facilitates high resolution, because single structural features can measure as small as 100 nanometers (billionths of a meter). The researchers produced hierarchically composed micro- and nanometer-scale structures, and the resulting surfaces emulated the butterflies' blue iridescence. ...'
