The gelation of r2 hydrogels after extrusion was compared with non-extruded sample. For this purpose, hydrogel precursor components were mixed in a syringe mixing system, kept for curing in the syringe for 48 h at room temperature, and then extruded directly onto the rheometer plate. A dynamic oscillatory time sweep was conducted at 1 Hz oscillation frequency, 1 % oscillation strain, and 25 °C with constant axial load of 100 mN using a 20 mm stainless steel parallel plate geometry and compared with hydrogel that was extruded onto the rheometer plate directly after mixing of the components.
