We present an experimental study of double-pulse laser-induced forward transfer (LIFT) and jet formation from different metal donor films. The dynamics of the jet formation and propagation have been investigated by time-resolved shadowgraphy studies. The morphologies of the irradiated films have been studied by means of scanning electron microscopy analysis. The experiments have been performed with copper, gold and nickel-copper double-layer films and the results point out the ability of double-pulse LIFT method to form long liquid metal jets and to print micro-droplets with a limited dependence on the metal properties.
