Researchers from the Beckman Institute have developed a chameleon-inspired 3D printing technique that lets you print multiple colors from a single ink polymer. How so? It utilizes ultraviolet light to selectively modify the surface structure of the crosslinking polymers as it’s being dispensed.
This technique enabled researchers to produce structural colors in the visible wavelength spectrum from deep blue to orange. Rather than use many different paints to achieve this color gradient like an artist would, the team only needs a single ink and then modifies how it is printed to create the same effect

By designing new chemistries and printing processes, we can modulate structural color on the fly to produce color gradients not possible before,” said Ying Diao, an associate professor of chemistry and chemical and biomolecular engineering at the University of Illinois Urbana-Champaign.
