3D bioprinting has emerged as a promising technology for several applications, including but not limited to the creation of complex organ-like structures, strategies for regenerative therapies, drug screening or novel drug delivery systems. However, the development of optimal hydrogel-based bioinks is one of the significant challenges that 3D biofabrication technology must accomplish. To this end, the combination of biomaterials used to design printable hydrogels is surprisingly important and must be carefully adjusted to meet the psychochemical and biological requirements for 3D bioprinting.

This special issue aims to gather the latest advances in the design and development of optimal hydrogel-based bioinks for 3D Bioprinting. We welcome original research and review articles that may contribute to increasing knowledge and discussion on this topic.
