"UV-assisted direct-ink-write 3D printing, altering structurally vibrant and potentially more sustainable colors from deep blue to orange, inspired by chameleons... single ink's color modifiable on the fly producing color gradients not possible before, by tuning light to control evaporative assembly of specially designed crosslinking polymers, nano-textured surfaces interfering with visible light... the single ink and modifies how it is printed to create the color gradient at the. molecular level"
