Abstract
A metal powder-based manufacturing system is provided and comprises: a sealed vessel defining a manufacturing chamber; a metal transformation/conversion unit contained in the manufacturing chamber and configured to heat a metal-based feedstock for transformation/conversion; an inert gas source in gas communication with the manufacturing chamber to supply inert gas therein, the inert gas source being operatively connected to the manufacturing chamber through an inert gas line; and at least one gas purifying unit in gas communication with the manufacturing chamber to purify the inert gas to obtain a purified inert gas having an oxygen partial pressure below about 100 ppb. A process for transforming/converting metal in a purified inert gas atmosphere.
