3D-Printed Imitation Skin Could Replace Animal Testing | The imitation skin is equipped with living cells and could be used for testing nanoparticle-containing cosmetics.
Researchers have developed a 3D-printable material that mimics the three-layer structure and mechanics of human skin. When printed with living cells, these skins could replace animals in the testing of cosmetics.
A team of researchers from Graz University of Technology (TU Graz) and the Vellore Institute of Technology (VIT) in India is working on the development of skin imitations that mimic the native three-layer tissue structure and biomechanics of human skin. “The hydrogels for our skin imitation from the 3D printer have to fulfil a number of requirements,” says Karin Stana Kleinschek from the Institute of Chemistry and Technology of Biobased Systems at TU Graz. After successful stabilisation, the cooperation partners in India test the resistance and toxicity of the 3D prints in cell culture.
