Abstract
An apparatus includes a wall that defines a shaft, a powder platform configured to support a powder bed within the shaft and configured to move through the shaft, and a sealing device that is in a compressed state from an outer perimeter of the sealing device to an inner perimeter of the sealing device such that the outer perimeter contacts the wall and the inner perimeter contacts the powder platform to form a seal between the powder platform and the wall. Another apparatus includes a wall that defines a shaft, a powder platform configured to support a powder bed within the shaft and configured to move through the shaft, and a sealing device comprising a non-fibrous material that is affixed to the powder platform and extends away from the powder platform, the sealing device contacting the wall to form a seal between the powder platform and the wall.
