Abstract

Official abstract text for this publication.

A additive manufacturing system includes a containment housing operable to form a containment chamber with a low pressure operating atmosphere and an additive manufacturing build housing within said containment housing.

First claim

Opening claim text (preview).

The invention claimed is: 1. An additive manufacturing system, comprising: a containment housing with a low pressure operating atmosphere containment chamber; a multiple of additive manufacturing build chambers within said containment housing, said containment chamber completely contains an additive manufacturing build housing that defines said multiple of additive manufacturing build chambers, said multiple of additive manufacturing build chambers contains a positive pressure therein greater than said low pressure operating atmosphere; and a filter system in communication with said build housing; and an inert gas source to communicate said inert gas into said build housing, said filter system within said containment chamber. 2. The additive manufacturing system as recited in claim 1 , wherein said containment housing is configured to provide the low pressure operating atmosphere is about 10{circumflex over ( )}−2 to 10{circumflex over ( )}−4 torr partial pressure. 3. The additive manufacturing system as recited in claim 1 , wherein said containment housing is configured to provide the low pressure operating atmosphere is about 10{circumflex over ( )}−3 to 10{circumflex over ( )}−4 torr partial pressure. 4. The additive manufacturing system as recited in claim 3 , wherein said build chamber receives an inert gas flow. 5. The additive manufacturing system as recited in claim 4 , wherein said inert gas flow is about 10 liters per minute. 6. A method of operating an additive manufacturing system, comprising: additively manufacturing within a multiple of additive manufacturing build chambers, the multiple of additive manufacturing build chambers within a containment housing having a low pressure operating atmosphere, said low pressure operating atmosphere is about 10{circumflex over ( )}−2 to 10{circumflex over ( )}−4 torr partial pressure; and compensating for a change in the pressure within the containment housing in response to a change in pressure in at least one of the multiple of additive manufacturing build chambers. 7. The method as recited in claim 6 , wherein the additive manufacturing build chamber is formed within an additive manufacturing build housing, the additive manufacturing build housing completely contained within the containment housing. 8. The method as recited in claim 7 , further comprising communicating an inert gas into the additive manufacturing build housing, a positive pressure build chamber within said additive manufacturing build housing greater than said low pressure operating atmosphere.
