Abstract: An exhaust manifold for an additive manufacturing system includes a manifold housing, at least one baffle movable relative to the manifold housing configured to modify an exhaust flow area defined in part by the at least one baffle, and an actuator operatively connected to the at least one baffle configured to move the at least one baffle. The manifold housing defines a housing channel. The at least one baffle can be one or more moveable baffles at least partially disposed within the housing channel and configured to move relative to the housing to modify a respective exhaust flow area of a respective baffle of the one or more moveable baffles. The actuator is operatively connected to each of the one or more movable baffles and configured to move the one or more movable baffles relative to the housing.

Abstract: A gas shield for an additive manufacturing system includes a bracket and a flexible curtain mounted to the bracket. A method of additively manufacturing includes removably mounting a gas shield to at least partially segregate a powder dispenser and a chamber.

Abstract: A powder recoater for an additive manufacturing machine can include a body, a recoater blade extending downwardly from the body, and at least two distance probes attached to the body and configured to determine a distance to a build plate to determine if a recoater blade is parallel to the build plate and/or if a build plate is level. The at least two distance probes can be touch probes configured to determine if a build plate is contacting one or more of the probes. Any other suitable probe type is contemplated herein.
