CONTROL OF LASER ABLATION CONDENSATE PRODUCTS WITHIN ADDITIVE MANUFACTURING SYSTEMS

摘要

Byproduct condensate generated during additive manufacturing is controlled by providing at least one electrode inside a chamber. The condensate may be electrically charged as it is generated or an electrical charge may be imparted to the condensate. The electrode may have either a positive or negative bias to either attract or repel the condensate. The electrode may be located on a wall of the chamber or associated with a transparent window through which a laser beam passes into the chamber.
