Estimating the term…
Nozzles for an additive manufacturing device and methods for improving wettability of the nozzles are disclosed. The method may include subjecting the nozzle to a surface treatment. The surface treatment may include contacting a surface of the nozzle with one or more surface modifying agents. The surface modifying agents may include one or more of an oxidizing agent, an acid, a base, or combinations thereof. The one or more surface modifying agents may increase an oxygen content of the surface of the nozzle. An inner surface of the nozzle may have a water contact angle of greater than 1° and less than about 90°. The inner surface of the nozzle may be free or substantially free of a coating.
A method for modifying wettability of a nozzle for an additive manufacturing device, the method comprising subjecting the nozzle to a surface treatment, wherein the surface treatment comprises contacting a surface of the nozzle with one or more surface modifying agents, wherein the one or more surface modifying agents increase an oxygen content of the surface of the nozzle, wherein the nozzle is fabricated from one or more graphitic materials, and wherein the surface modifying agents comprises one or more of an oxidizing agent, an acid, a base, or a combination thereof.
