Abstract
A method of additive manufacturing an article from a feed material in a chamber includes evacuating at least some of a first gas from the chamber, thereby reducing a pressure therein from a first pressure to a second pressure and reducing the first gas from a first concentration to a second concentration. At least some of the first gas is then gettered from the chamber using a getter, thereby lowering the first gas concentration to a third concentration. The article is then additive manufactured from the feed material in the chamber using the getter as a substrate. The gettering comprises heating the getter at least in part using a fusion source, and the additive manufacturing comprises heating the feed material at least in part using the fusion source.
