Abstract
Improved manufacturing using a printer that deposits a liquid to fabricate a layer having specified thickness includes automated adjustment or print parameters based on ink or substrate characteristics which have been specifically measured or estimated. In one embodiment, ink spreading characteristics are used to select droplet size used to produce a particular layer, and/or to select a specific baseline volume/area or droplet density that is then scaled and/or adjusted to provide for layer homogeneity. In a second embodiment, expected per-droplet particulars are used to interleave droplets in order to carefully control melding of deposited droplets, and so assist with layer homogeneity. The liquid layer is then cured or baked to provide for a permanent structure.
