An overview of extrusion-based bioprinting with a focus on induced shear stress and its effect on cell viability

Three dimensional bioprinting is an emerging fabrication technique in the field of tissue engineering. Extrusion-based bioprinting is one of the widely employed biofabrication techniques; researchers tend to use it because of its simplicity, affordability and scalability. During the extrusion-based bioprinting process, cells are subjected to mechanical forces of different kinds. Among these mechanical forces, shear stress is of a special...
