1. A printing device for depositing material on a heated substrate, the device comprising:
- a substrate surface;
at least one print head spaced from the substrate surface and comprising a plurality of nozzles configured to print metallic material;
a heat shield comprising a shield plate and a shield frame for maintaining the shield plate at a fixed position between the substrate surface and the at least one print head; and
one or more coolant ducts positioned within the shield frame and configured for flowing coolant fluid through the shield frame, wherein the coolant fluid is circulated to a reservoir to convey heat away from the heat shield and inhibit heat transfer from the heated substrate to the at least one print head.

Abstract
A printing device for dispending material on a heated substrate is provided. The device may include a printing head having one or more nozzles and a heat shield that partially masks a side of the printing head that faces the heated substrate when printing so as to reduce heat transfer from the substrate to the printing head. The shield includes a slot aligned with the one or more nozzles to enable passage of material from the one or more nozzles to the heated substrate.
