Zusammenfassung:	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.
