A ‘living tattoo’ could be used to reproduce tissue and even improve organ health. The 3D printing technique of the past had little chance of improving tissue health, due to the UV light and radiation that the printer emits during the printing process, but all of that has changed.
The researchers also believe that the technique can manufacture drug capsules and surgical implants in the near future, too. Can use bacterial cells like workers in a 3D factory. They can be engineered to produce drugs within a 3D scaffold, and applications should not be confined to epidermal devices. As long as the fabrication method and approach are viable, applications such as implants and ingestibles should be possible.
