1. A dross extraction system for a metal-jetting printer, comprising: an ejector defining an inner cavity associated therewith, the inner cavity retaining a liquid printing material; a first inlet coupled to the inner cavity configured to introduce printing material into the inner cavity of the ejector; a second inlet coupled to the inner cavity further comprising an inlet sleeve; and a probe external to the ejector, selectably positionable within the inlet sleeve to contact the liquid printing material to attract dross thereto, thereby extracting dross from the liquid printing material when the probe is withdrawn from the liquid printing material via the inlet sleeve.
