The medicine of the future is biological: damaged tissue will be replaced by biologically functional tissue from the 3D printer. A team of researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has been developing and optimising bio-inks suitable for additive production for years in cooperation with the University of Stuttgart. By varying the composition of the biomaterial, the researchers can expand their portfolio to include bone and vascularisation inks. The researchers have thus laid the foundations for the production of bone-like tissue structures using capillary networks.
