| Laser Induced Forward Transfer (LIFT) is a direct-write laser technique, suitable for transferring materials with a great range of viscosities (from Newtonian fluids to solid mate- rials) in different sizes onto a number of substrates. LIFT process has some attractive features such as easy setup, high flexibility to print free form geometries and cost-effectiveness that have done feasible its industrial implementation. We discuss the mechanisms for the material transfer both in ns and ps regimes of irradiation of these high viscosity materials, using high speed imaging techniques and numerical simu- lations. We present two applications of LIFT and show their possible industrial scalability. The first one is the large area metallization using LIFT using silver-based pastes initially de- signed for solar cell screen printing and the potential use of this technique in the photovoltaic industry (both in standard c-Si solar cells and thin film technologies) and flexible electronics devices. Demonstrating that it is capable of improving the aspect ratio and, in addition, of fulfilling the requirements imposed by the mechanical properties of the substrates in flexible electronic applications. We also present how this experience has been applied for precise 2D patterning in large areas at high speed is possible for a great variety of fluids with different viscosities, including high viscosity fluids. We show how it is possible to develop laser-based bioprinting applica- tions using with high throuhput, large area, repeteability and low cost. | |
