Depicts the fluid flow, bioink adsorption and evaporation flux of bioink under uncontrolled and controlled humidity levels, during air drying on each stamp feature. B) A comparison of moisture level, evaporation flux and air-drying time between uncontrolled and controlled humidity environments. C) SNRs after µCP stamps under controlled relative humidity levels of 20%, 40%, 60% and 80%, at dry times of 1 min, 2 min, 3 min and 4 min. Error bars calculated using standard error of the mean. D) Fluorescence images of each relative humidity level at 3 min dry time. Scale bars were 100 µm. E) SNRs after µCP stamps using applied forces of 0 kPa, 8.17 kPa, 16.33 kPa, 32.67 kPa, 40.82 kPa, 49 kPa. Error bars calculated using the mean of standard deviation. F) Fluorescence images of each force applied with optimized bioink and external environment conditions. Scale bars were 100 µm.
