printing resolution, speed, and reproducibility for a wide variety of materials. This
was exploited not only by the academia but from the industry as well since in the last
5 years the technique has been exploited for commercial purposes. For example in
2011, Daetwyler launched a digital laser printing solution called LaserSonic [137]
under the banner “DI Project AG,” which was a joint venture of the companies
Interprint and Daetwyler. In addition, Orbotech Ltd. has launched the Precise™ 800
system [138] that is the first solution for advanced High-Density Interconnect (HDI)
and complex multi-layer PCB manufacturing and is capable of both removing excess
copper and also depositing missing copper. Moreover, in the biomaterial industry
Poietis offers a laser-assisted bioprinting solution [139] that relies on the principles
of 3D printing and allows the precise 3D positioning of cells as well as extracellular
matrix via a layer by layer assembly approach with micrometer resolution. Finally,
ALPhaNOV [140] is already participating in a research project, where its main goal
is to validate the methodology for laser-assisted biological materials printing for
in vivo bone tissue engineering in mice.
9.8 Conclusions
The progress of laser printing technology and specifically of the LIFT technique was
presented in this chapter with the aim to provide a complete overview on the important findings and applications that have been made up to date. The evolution that
has been made since LIFT’s first reporting has enabled LIFT to be incorporated into
the development of several different applications such as chemical and biological
sensors, OLEDs, OTFTs, electrical interconnects etc. Moreover, the unique advantages of LIFT namely selectivity, high-spatial resolution and versatility along with the
complementarity of the technique with other laser processes including laser sintering,
ablation, etc. enable the fabrication of all-laser printed devices in a rapid and costeffective way and this has been already exploited for industrial purposes as it was
mentioned in the last paragraph.
