Abstract
A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.
Claims13
An additive manufacturing system comprising:
- an enclosure restricting an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure, wherein gaseous oxygen within the enclosure is maintained at below atmospheric level;
- an airlock interfacing between the exterior and the interior and sized to enable one or more human operators to pass through;
- and
- a plurality of machines located within the enclosure, each machine of the plurality of machines comprising:
- a separate powder bed exposed to the gaseous oxygen within the enclosure, and
- a control system programmed to execute an independent process of powder fusion at the powder bed.
