Figure 3. Simulation of the extrusion process and nozzle disturbance. (a) Effect of ambient temperature on outlet temperature. (b) Changes in the flow
velocity within the nozzle during bioink extrusion. (c) Flow velocity in the center of the nozzle when the inlet pressure was varied. (d) Flow velocity (d1)
and mass flow rate (d2) at the outlet of the nozzle with different diameters. (e) Change in velocity caused by the movement of the nozzle in support baths
with different concentrations of gelatin/alginate (G/A) microparticles and oxidized alginate (OAlg). (f) Velocity cloud maps when the nozzle moved at the
speed of 20 mm/s in support baths with concentrations of 80% (f1) and 40% (f2). (g) Disturbance range caused by the nozzle moving at different speeds in
support baths with different concentrations of G/A microparticles and OAlg.
