Abstract
A system and method for additive manufacturing are provided. The system includes a structure defining a chamber for manufacturing parts via additive manufacturing. A powder metal applicator is configured to deposit layers of powder metal material to build a part on a build platform. A laser source is configured to direct one or more laser beams onto each layer of powder metal material to fuse the powder metal material, wherein metal condensate is created by the laser beam(s) contacting the powder metal material. An element spaced apart from the layers of powder material has a temperature different than the chamber temperature, so that the element is configured to attract or repel the metal condensate by virtue of the temperature differential between the element and the chamber. The method includes using the element having the different temperature to attract or repel the metal condensate within the chamber.
