Abstract
A solid freeform manufacturing system includes a manufacturing chamber containing a powder based additive manufacturing device. The manufacturing chamber is connected to an environmental control chamber. The environmental control chamber contains environmental control devices including fans, filters, and an inert gas source. An interconnection between the environmental control chamber and manufacturing chamber allows an inert, contaminant free manufacturing environment.
