Now working intensively on cross-linking methods to stabilize the 3D-printed skin, Austrian researchers aim to follow a natural approach, ensuring the process occurs under very mild conditions and without the use of cytotoxic chemicals. Once they achieve successful stabilization, the team in India begins testing the durability and potential toxicity of the 3D-printed skin models in cell cultures.
A structure can only be considered a true skin imitation once the skin cells embedded in the hydrogel survive in cell culture for two to three weeks and begin forming actual skin tissue. Only then can it be used for further cellular testing of cosmetic products
