Future Perspectives for Gel-Inks for 3D Printing in Tissue Engineering

Medicine has evolved over time from diagnostic methods, has gone through the development of treatments (initially natural, then based on synthesis substances) and reached at the beginning of the twentieth century to the development of biomaterials. Towards the end of the twentieth century, a new field slowly made its way between medical sciences and that of tissue engineering. Ideally, tissue engineering is that inter and multidisciplinary science that aims to design and obtain parts of tissues or even organs in their entirety. This book presented in previous chapters the current level of research in the field of hydrogels as precursors for 3D printing with obtaining constructions for tissue engineering. This chapter aims to present some of the challenges that 3D bioprinting will have to face in order to solve some of the challenges of current regenerative medicine. The main directions are presented both from the point of view of the precursors used, as well as from the point of view of the organs or specific challenges that will have to be solved.
