Abstract: Many embodiments described herein are directed to a printing nozzle capable of producing a high-pressure flow of shielding gas that surrounds a lower pressure flow of shielding gas of the central channel. In certain embodiments, the high-pressure shield gas flow in the internal channels can blow out the material buildup in the nozzle. The high-pressure shielding gas can be concentrically produced around the first low-pressure shielding gas such that it helps to force the first shielding gas into a more laminar flow around the feed material. In several embodiments, a second low-pressure flow of shielding gas can be produced using a secondary cup to increase shielding gas coverage. In various embodiments, a secondary cup surrounds the inner cup, where the gas flow in the central channel and the outer channel can provide shielding gas coverage for the nozzle during printing.
