Abstract Scope |
Aerosol jet printing (AJP) is a type of non-contact direct-ink write technology used for fabrication of micro-electronics. Coupling the geometrical freedom and high-resolution characteristics inherent to the process, AJP can be used to tailor conductive traces for (1) embedded strain and temperature sensors on additive manufactured substrates and (2) advancing research and design of these embedded sensors onto 3D “free form geometries”. Specifically, this project investigated print parameters for (non-nanoparticle) reactive silver ink on polyimide and fused filament fabricated (FFF) substrates. A strain gauge geometry was repeatedly printed using non-nanoparticle ink with two different aerosol jet printers, the Optomec AJ5X and IDS Nanojet. Post print characterization found print parameters influenced material deposition. In addition, pre-print surface cleaning of substrates influenced consistency of printed patterns and reduced variability in resistance values. A smooth surface of FFF polylactic acid substrates is needed to achieve measurable resistance of the AJP geometry. |
