Abstract: An aerosol-based printing apparatus is provided capable of producing an aerosol stream at a constant rate and constant material deposition to a substrate to provide high-definition, high-resolution traces. The aerosol-based printing apparatus provides production, transport, and delivery of an aerosol stream at a constant rate for a period of time of at least 8 hours and other instances more than 24 continuous hours of constant operation. By inhibiting bulging and necking of the deposited trace, superior line width tolerances are achieved, and such tolerances are maintained for extended periods of time, thereby allowing for both the deposition of complex traces as well as consistent manufacture of duplicate articles that maintain the tolerances across a production ran. The accumulation of fluids in the aerosol and gas transport conduits are eliminated, thereby eliminating the need for purge or cleaning cycles and allowing for uninterrupted operation for a minimum of 24 hours.
