Abstract

Blister-actuated laser-induced forward transfer (BA-LIFT) is a high-resolution printing technique, where small droplets are ejected from a thin liquid layer onto a receiver substrate. Experiments with a high-speed camera imaging setup demonstrate novel regimes during the jet formation for the transfer of viscoelastic shear-thinning polymer solutions compared to Newtonian fluids. The ratio of the ink film thickness Hf to the blister height Hb is used as a dimensionless number Hf/ Hb to classify different jet behaviors. We show that different Hf/ Hb thresholds can be defined depending on the elasticity of the ink layer for the induced jets to result in breakup.
