WebFeb 19, 2024 · A bioink's viscosity, shear-thinning, and thixotropic behaviors can be measured through rheology, and several mathematical models relating these measurements to extrudability and cell damage have been well-established [26, 45, 46]. As such, rheological characterizations can be successfully used as indirect measures of extrudability. WebUsing commercially available 3D printers, a groove was created and used to deposit low viscosity bioink on the surface of the printed thermoplastic. The traditional extrusion methods utilized high viscosity materials, and this groove provided a suitable space for biomaterial deposition. In this way, the investigators were able to use a wide ...
