Rheological study on 3D printability of alginate hydrogel and effect of graphene oxide

In recent years, hydrogels have been used as important biomaterials for 3D printing of three dimensional tis-sues or organs. The key issue for printing a successful scaffold is the selection of a material with a good printability. Rheological properties of hydrogels are believed to pay an important role in 3D printability. However the relations be-tween rheological properties of hydrogels and 3D printability have not been extensively studied. In...
