The development and atomization of inks have a considerable effect on the printing quality. Therefore, in this study, the effect of a specific ratio of silver nanoparticle ink and a co-solvent of propylene glycol monomethyl ether (PGME) and ethylene glycol (EG) was investigated. The results indicated that the proportion of the solvent in the silver nanoparticle ink could affect the electrical characteristics of the printed lines. The prepared conductive ink with 95% silver nanoparticle ink and 5% co-solvent at a curing temperature of 180 °C demonstrated superior electrical conductivity and adhesion on the substrate. © 2020, Springer-Verlag London Ltd., part of Springer Nature.3D printers; Aerosols; Ethylene; Ethylene glycol; Metal nanoparticles; Organic solvents; Polyols; Silver nanoparticles; Aerosol jet printings; Curing temperature; Electrical characteristic; Electrical conductivity; Ink modification; Monomethyl ethers; Printing technologies; Propylene glycols; Ink jet printing[SDGs]SDG9journal article10.1007/s00170-020-06186-w2-s2.0-85092388850
