Abstract
A hopper for dispensing powder material for an additive manufacturing system includes a gate that is movable along a first direction to open and close a discharge slot and which is pivotable about a pivot axis transverse to the first direction. The first direction can be a horizontal direction and the pivot axis can be parallel to a vertical direction. The gate can have a portion that contacts the hopper, e.g., at a surface including the discharge slot, and is elastically deformed with movement from the open to the closed position.
