Drop on demand (DoD) inkjet printing is a high precision, non-contact and maskless additive manufacturing technique employed in producing high precision micrometer-scaled geometries allowing a free design manufacturing for flexible devices and printed electronics. This study investigates the influence of the main printing parameters (namely, the spacing between subsequent drops deposited on the substrate, the printing speed, and the nozzle temperature) on the dimensional accuracy of a representative geometry consisting of two interlocked comb shapes. The study objective was achieved thanks to a proper experimental campaign, which was developed according to Design of Experiments (DoE).
