Dross Mitigation Method And Device in A MHD Printer

Abstract

The present disclosure discloses methods and systems for removing dross from a liquid metal chamber, such as would be used in magnetohydrodynamic (MHD) or metal 3D printing. The method and systems comprise inserting a dross removal tool into a liquid metal chamber. A seal is compromised, fluidically connecting an evacuated volume and the liquid metal chamber. Pressure equalizes between the fluidically coupled volumes through an inflow of gas, liquid, and solid components from the liquid metal chamber into the dross removal tool. The dross removal tool is removed from the liquid metal chamber.
