A Mixing System for Uniform, Reproducible Viscous Bioinks Preparation.

Rationale: Extrusion 3D bioprinting is an additive manufacturing tissue engineering technique that uses cell-laden viscous biomaterials known as bioinks. Manually mixing cell suspensions into viscous biomaterials can be challenging due to the high viscosity ratio between the two fluids. Static mixers are an attractive approach as they can quickly and reproducibly mix two fluids, including those with a high viscosity ratio. However, static …
