Title (EN) TWO-PART PLATFORM SEAL
(FR) JOINT DE PLATE-FORME EN DEUX PARTIES
Abstract:
(EN) 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.
(FR) Un exemple de joint à deux parties pour une imprimante 3D à base de poudre comprend un racleur de film souple fixé à une plate-forme rectangulaire et disposé sur des segments linéaires d'un périmètre de la plate-forme. Le racleur de film flexible s'étend au-delà du périmètre de la plate-forme pour fournir un joint coulissant contre les parois correspondantes d'une enceinte rectangulaire de la plate-forme. Le joint en deux parties comprend également un élément déformable disposé sur le racleur de film flexible qui s'étend au-delà du périmètre de la plate-forme pour appliquer une pression d'étanchéité au racleur de film flexible.
