Stability curves for the population of micro bubbles in relation to time at room temperature of 22 ° C and a pressure of 91 KPa and the liquid phase with a viscosity of 2.24 mPa.s. (a) Stability curve of the population of micro bubbles generated by the 3D printing-based device, to a mean diameter of 313.04 μm. (b) Stability curve of the population of micro bubbles generated by the hybrid device to a mean diameter of 73.74 μm .
