Zusammenfassung:	An example two-part seal for a powder-based 3-D printer includes a flexible film wiper attached to a rectangular platform and disposed on linear segments of a perimeter of the platform. The flexible film wiper extends beyond the perimeter of the platform to provide a sliding seal against corresponding walls of a rectangular enclosure of the platform. The two-part seal also includes a deformable member disposed upon the flexible film wiper that extends beyond the perimeter of the platform to apply sealing pressure to the flexible film wiper.
