Beschreibung
Zusammenfassung:	An additive manufacturing (AM) system includes a housing defining a chamber, a build platform disposed within the chamber, and an upper gas inlet configured to supply an upper gas flow in a first direction parallel to the build platform. The AM system includes a lower gas inlet disposed in the chamber and configured to supply a lower gas flow in a second direction toward a bottom wall of the chamber, and a flow directing system configured to receive the lower gas flow and redirect the lower gas flow in the first direction parallel to the build platform. The AM system includes one or more gas delivery devices fluidly coupled to the upper and lower gas inlets and configured to regulate one or more flow characteristics of the upper and lower gas flows and a gas outlet configured to discharge the upper and lower gas flows from the chamber.
