Abstract: A method for forming a conductive pattern on a substrate deposits, onto a surface of the substrate, a nanoparticle ink that comprises nanoparticles of a conductive or semiconductor material, at least one low boiling point solvent, and from 0.1 weight % to 50 weight % of a high boiling point solvent. The method forms a partially wet patterned substrate by drying the deposited nanoparticle ink to a wetness range between about 3 weight % and 8 weight % solvent. The method directs a patterned illumination of laser light to cure the deposited ink pattern on the partially wet patterned substrate.
