Simulation of direct and blister-assisted laser-induced forward transfer techniques

Abstract

In Laser-Induced Forward Transfer (LIFT), fluid motion is a complex hydrodynamic phenomenon. In the case of LIFT of high-viscosity fluids, the formation of a stable hollow column between the donor and the acceptor substrates takes place, whereas the transference of low-viscosity fluids through Blister-Assisted LIFT (BA-LIFT) leads to secondary effects that have not been already explained, such as secondary jets or bulgy shapes. In this work, every reported regime has been modeled through a Phase Field FEM model for both LIFT and BA-LIFT.
