Scientists say they have made a vivid 3D printing ink without dyes and pigments
- The biocompatible ink is safe for use in toys that change colour or even food decorations, though it’s not yet edible, according to Chinese team
- New technology is based on structural colouration – meaning it produces colours through interactions between light and intrinsic nanostructures
