1. An unitary defroster system for a motor vehicle windshield and formed by an additive manufacturing process comprising:
an instrument panel substrate; and
an air supply plenum terminating in a plurality of individually configured defroster nozzle ducts conjoined with the instrument panel substrate and aligned in a substantially linear row parallel to and disposed proximate an interior surface of the windshield;
wherein the ducts are configured and arranged to deliver a substantially uniform air flow pattern to the interior surface of the windshield,
wherein at least one of the plurality of individually configured defroster nozzle ducts conjoined with the instrument panel substrate has a configuration comprising a reduced cross-sectional profile proximate a discharge opening of the one of the nozzle ducts; and
wherein the reduced cross-sectional profile proximate the discharge opening of the one of the nozzle ducts comprises an increased wall thickness of a portion of the nozzle duct vertically disposed proximate to and below an outer surface of the instrument panel substrate.
