DROSS REMOVAL METHODS AND DEVICES FOR MAGNETOHYDRODYNAMIC JETTING OF METALS IN 3D PRINTING APPLICATIONS

Abstract:

A dross removal system for magnetohydrodynamic additive. A vacuum source is used to create a pressure differential at a nozzle opening sufficient to collect dross from a pool of molten metal. The dross and any collected molten metal can be captured in a waste bin for later disposal. 308
