“…76 Soltman et al also showed that proper drop registration scheme can help preserve the pattern definition of the printed liquid films (Fig. 5), [76][77][78] and the receding contact angles of liquids on the substrate surfaces are of crucial importance to the accuracy of printed features. 79 With the addition of co-solvent adjustments, one can also adjust the contact angles to preserve the pattern definition.…”

This review briefly summarizes the recent development in fabrication of conductive tracks with inkjet printing technology. Special emphasis will be placed on material selection and printing procedures. Troubleshooting guidelines for frequent problems in inkjet printing methods, such as material selection, ink formulation, ink-substrate interaction, and post-treatment of inks, are elucidated in this article to fabricate conductive tracks or electrodes with well-defined patterns. Related applications and unsolved challenges are also briefly reviewed in this article.

“…Although inkjet is a simple, non-contact direct-write method, it is usually limited to the transfer of low viscosity, chemically benign nanoparticle suspensions in order to avoid clogging and/or corrosion of the dispensing nozzles. In addition, printing patterns with well-defined edge features by inkjet is very difficult given the variable behavior of fluids on different surfaces and their resulting instability due to wetting effects 13 . Regardless, inkjet has enjoyed the most attention from researchers thus far.…”

Over the past decade, there has been much development of non-lithographic methods 1-3 for printing metallic inks or other functional materials.Many of these processes such as inkjet 3 and laser-induced forward transfer (LIFT) 4 have become increasingly popular as interest in printable electronics and maskless patterning has grown. These additive manufacturing processes are inexpensive, environmentally friendly, and well suited for rapid prototyping, when compared to more traditional semiconductor processing techniques. While most direct-write processes are confined to two-dimensional structures and cannot handle materials with high viscosity (particularly inkjet), LIFT can transcend both constraints if performed properly. Congruent transfer of three dimensional pixels (called voxels), also referred to as laser decal transfer (LDT) [5][6][7][8][9] , has recently been demonstrated with the LIFT technique using highly viscous Ag nanopastes to fabricate freestanding interconnects, complex voxel shapes, and high-aspect-ratio structures. In this paper, we demonstrate a simple yet versatile process for fabricating a variety of micro-and macroscale Ag structures. Structures include simple shapes for patterning electrical contacts, bridging and cantilever structures, high-aspect-ratio structures, and single-shot, large area transfers using a commercial digital micromirror device (DMD) chip.

“…For this reason it has received increasing attention in the biotechnological and pharmaceutical fields since it enables performing complex analysis on small amounts of material, which are often expensive or in limited supply. A frequent issue in dispensing biological solutions onto flat substrates deals with control of size, shape and relative distance of dots as well as alignment and regularity of realized micro-arrays which occurs when spots are formed with a large number of droplets [11]. As a solution, preliminary micro-patterning of the substrate has been proposed [12].…”

a b s t r a c tWe present an innovative technique to dispense precise amounts of polymer solutions into large arrays of microscopic wells. An inkjet printer (NP 2.1 GeSim, Germany) is used to fill micro-wells with poly (vinyl pyrrolidone) (PVP K10). The micro-wells are fabricated with cavity diameters of 300 lm down to 50 lm with SU-8 with two steps of negative photolithography. Inkjet printing is shown to be a suitable technique to dispense defined volumes of solution (down to 0.3 nL) in a highly reproducible way. The filling with polymer can be controlled varying the concentration of the solution and the number of dispensed droplets. Solutions of up to 20 wt.% PVP in water are successfully spotted.
