A powder removal apparatus includes an extraction housing comprising a sidewall that is sized and configured to extend around a powder bed of a build module and a top wall that is sized and configured to extend between opposite sides of the sidewall and over the powder bed. The sidewall and top wall are configured to form a chamber portion of a turbulence chamber. The top wall has a vacuum exit opening that is configured to fluidly connect to a vacuum source. The sidewall has a plurality of sidewall inlet flow channels that extend from an inlet opening at an exterior side of the sidewall to an outlet opening at an interior side of the sidewall. A side exit channel is configured to extend along the top wall from a collector opening in communication with the chamber portion toward the vacuum exit opening.
