"Chameleon-Inspired 3D Printing: Infinite Colors from a Single Ink"
Researchers have developed a sustainable 3D-printing technique inspired by chameleons, allowing for the creation of multiple dynamic colors from a single ink by modulating structural color during the printing process. This approach utilizes specially designed crosslinking polymers and UV light to achieve color gradients in the visible spectrum, offering a more vibrant and potentially more sustainable alternative to traditional chemical pigments or dyes. The study, published in the journal PNAS, demonstrates the power of collaboration in designing this molecular-level system.
