ink without colourants that is safe to use in toys that change colour in relation to body temperature, or even for food decorations.
The researchers from Fudan University in Shanghai, Southeast University in Nanjing and the University of Chinese Academy of Sciences in Wenzhou published their findings in the peer-reviewed journalUnlike conventional 3D colour printing ink – which uses dyes or pigments that can fade – the new technology is based on structural colouration, said lead author Shang Luoran, an assistant professor with the Institutes of Biomedical Sciences at Fudan University.
They developed the printable, structural colour ink using cholesteric cellulose liquid crystals , gelatin and a hydrogel. Shang said these materials were all readily available and compatible with existing 3D printers, adding that the team aimed to improve the formula to make the ink edible.
