Influence of layer thickness and viscosity on droplet volume. Plots a) - c) show the dependence of the droplet volume on the laser energy and the initial hydrogel layer thickness on the donor slide. Dashed lines illustrate the linear trend of the data points and the error bars mark the standard deviation. For the time-resolved images in d) a solution with η = 0.4311 Pa·s was imaged at different layer heights. The temporal delay in all these images was 100 μs and the laser energy was kept constant at 17 μJ.
