Researchers have created a sustainable approach for 3D printing inspired by chameleons' colour-changing abilities

The study coducted by University of Illinois Urbana-Champaign has been published in the journal PNAS

Study author Ying Diao said that new technology can modulate structural colour on the fly "to produce colour gradients not possible before"

Scientists used structural colour, a scientific phenomenon, that absorbs and reflects light, and manipulates a material's physical arrangement

They then put it through a UV-assisted direct-ink-write 3D printing approach that tunes light to control the printing process

The team used specially designed crosslinking polymers for the research, which allowed them to alter structural colour

It was found that structural colours can be produced in the visible wavelength spectrum from deep blue to orange

While an artist might use many different paints to achieve a particular colour gradient, the research team used a single ink
