From chameleons a new multicolor 3D printing technique - Frontiers. The result is published in the journal of the American Academy of Sciences (Pnas) by the University of Illinois at Urbana-Champaign (ANSA) The researchers created this new 3D.

printing technique by taking the changing livery of chameleon as a model, whose color is due to the presence of nano-structures that reflect light differently. To reproduce them, the researchers developed a special ink that can be activated by light to form nanoscopic lamellar structures that generate vibrant structural colors.
