“…For example, bulging, a phenomenon common to other printing techniques, like inkjet printing, can seriously compromise the functionality of the printed element. Several strategies have been investigated to mitigate this effect, like overlapping sets of droplets with an intermediate drying step, or printing within fluidic guides previously generated by laser ablation . At high laser scan speeds (tens of m s −1 ) and repetition rates (1 MHz), the interaction between jets described in Section can surprisingly also help suppress bulging .…”

Laser‐induced forward transfer (LIFT) is a digital printing technique that uses a pulsed laser beam as the driving force to project material from a donor thin film toward the receiving substrate whereon that material will be finally deposited as a voxel. This working principle allows LIFT to operate with both solid and liquid donor films, which provides the technique with an unprecedented broad spectrum of printable materials, and thus makes it very competitive over other digital technologies, like inkjet printing. It is not only that LIFT can access a much wider range of ink viscosities and loading particle sizes; the possibility of printing from solid films allows the single‐step printing of multilayers and entire devices, and even makes possible 3D printing. This versatility translates, in turn, into a broad field of applications, from graphics production to printed electronics, from the fabrication of chemical sensors to tissue engineering. This monograph provides an extensive review of the LIFT technique, from its origins to the most recent achievements, focusing on the fundamental aspects of both its working principle and transfer dynamics, as well as on its broad range of applications.

“…Any defect, like a single discontinuity or any protuberance, compromises the performance of the full device. Accordingly, conductive inks are mainly involved in most of the LIFT studies dealing with the printing of continuous patterns [35,65,66,[71][72][73][74][75][76][77][78]. Nevertheless, studies on continuous line and homogeneous area printing have been also conducted with water-based suspensions in view of their interest in biosensors fabrication [79,80].…”

Laser-induced forward transfer (LIFT) is a direct-writing technique based in the action of a laser to print a small fraction of material from a thin donor layer onto a receiving substrate. Solid donor films have been used since its origins, but the same principle of operation works for ink liquid films, too. LIFT is a nozzle-free printing technique that has almost no restrictions in the particle size and the viscosity of the ink to be printed. Thus, LIFT is a versatile technique capable for printing any functional material with which an ink can be formulated. Although its principle of operation is valid for solid and liquid layers, in this review we put the focus in the LIFT works performed with inks or liquid suspensions. The main elements of a LIFT experimental setup are described before explaining the mechanisms of ink ejection. Then, the printing outcomes are related with the ejection mechanisms and the parameters that control their characteristics. Finally, the main achievements of the technique for printing biomolecules, cells, and materials for printed electronic applications are presented.

“…The LIFT process utilizes a pulsed laser beam as a driving force to transfer the material from the donor substrate to the acceptor substrate, which are in proximity [17,18]. The NPs transferred by a single pulse have a circular shape in general [19], and therefore, the single transfer has to be repeated at specific laser parameters and a proper hatch size to integrate each droplet and create continuous features [20,21]. Furthermore, unlike the SLS process, additional heat treatment is essential for these metal NPs to function properly as electrodes [20,22].…”

Furthermore, unlike the SLS process, additional heat treatment is essential for these metal NPs to function properly as electrodes [20,22]. Since the LIFT process and the SLS process use a pulsed laser and a continuous-wave (CW) laser, respectively, an additional furnace or another optical system is required for the heat treatment after the transfer step, which inevitably increases the overall manufacturing cost.…”

Continuous-Wave Laser-Induced Transfer of Metal Nanoparticles to Arbitrary Polymer Substrates

et al. 2020

Laser-induced forward transfer (LIFT) and selective laser sintering (SLS) are two distinct laser processes that can be applied to metal nanoparticle (NP) ink for the fabrication of a conductive layer on various substrates. A pulsed laser and a continuous-wave (CW) laser are utilized respectively in the conventional LIFT and SLS processes; however, in this study, CW laser-induced transfer of the metal NP is proposed to achieve simultaneous sintering and transfer of the metal NP to a wide range of polymer substrates. At the optimum laser parameters, it was shown that a high-quality uniform metal conductor was created on the acceptor substrate while the metal NP was sharply detached from the donor substrate, and we anticipate that such an asymmetric transfer phenomenon is related to the difference in the adhesion strengths. The resultant metal electrode exhibits a low resistivity that is comparable to its bulk counterpart, together with strong adhesion to the target polymer substrate. The versatility of the proposed process in terms of the target substrate and applicable metal NPs brightens its prospects as a facile manufacturing scheme for flexible electronics.
