Abstract
A fluid flow apparatus configured to provide a flow of fluid with particular flow profiles to a process chamber of an additive manufacturing apparatus is provided. The fluid flow apparatus includes a plurality of openings forming a first flow region, a second flow region, a third flow region, and a fourth flow region in adjacent arrangement along an axis in the process chamber between the build platform and the laser window. A controller is configured to execute instructions that perform operations that include flowing, via the second flow region, the flow of fluid along a second distance along the axis at a second velocity range between approximately 1.0 meters per second (m/s) and 6.0 m/s, and flowing, via the fourth flow region, another flow of fluid along a fourth distance along the axis at a fourth velocity range between approximately 0.1 m/s and 4.5 m/s.
