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.

15. 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 including a plurality of nozzles configured to print metallic material; a heat shield including 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 heat shield for flowing coolant fluid, wherein the coolant fluid is circulated to a reservoir for conveying heat away from the heat shield and preventing heat from the heated substrate from overheating the at least one print head. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
