“…However, the reliability of these methods and the range of ink materials that can be printed are ultimately limited by the presence of a nozzle, which can be subject to clogging and material compatibility issues. Alternatively, laser-induced forward transfer (LIFT) is an emerging highresolution printing technique, which can deposit a wide range of structural and functional materials without the use of a nozzle (Piqué et al 1999;Piqué et al 2006;Kyrkis et al 2006;Arnold et al 2007). In this process, a pulsed laser initiates the ejection of a small volume of ink from a thin liquid donor film (1-100 lm), which is supported by a laser-transparent glass substrate, onto a parallel receiver substrate held at a distance (10-1000 lm).…”

Laser-induced forward transfer (LIFT) is a high-resolution direct-write technique, which can print a wide range of liquid materials without a nozzle. In this process, a pulsed laser initiates the expulsion of a highvelocity micro-jet of fluid from a thin donor film. LIFT involves a novel regime for impulsively driven free-surface jetting in that viscous forces developed in the thin film become relevant within the jet lifetime. In this work, timeresolved microscopy is used to study the dynamics of the laser-induced ejection process. We consider the influence of thin metal and thick polymer laser-absorbing layers on the flow actuation mechanism and resulting jet dynamics. Both films exhibit a mechanism in which flow is driven by the rapid expansion of a gas bubble within the liquid film. We present high-resolution images of the transient gas cavities, the resulting ejection of high aspect ratio external jets, as well as the first images of re-entrant jets formed during LIFT. These observations are interpreted in the context of similar work on cavitation bubble formation near free surfaces and rigid interfaces. Additionally, by increasing the laser beam size used on the polymer absorbing layer, we observe a transition to an alternate mechanism for jet formation, which is driven by the rapid expansion of a blister on the polymer surface. We compare the dynamics of these blister-actuated jets to those of the gas-actuated mechanism. Finally, we analyze these results in the context of printing sensitive ink materials.

“…Existing technologies, such as these reported by Holmes [27,28], Karlitskaya et al [29,30] and Pique et al [12,[31][32][33][34], however, suffer from significant drawbacks which limit their applicability. Among them are the precision and accuracy of die placement.…”

“…Other authors present also Laser Induced Plasma Assisted Ablation (LIPAA) permitting engraving, inspired from LIFT and widely employed for micromachining and deposition of layers [4]. The literature concerning LIFT and the different combinations is vast: the readers can refer also to complete reviews [1,6,7] to know the different uses of this flexible technology. The first report of patterned metal deposition with LIFT was given by Bohandy et al [8].…”
