Title (EN) CHANGING CHAMBER FOR A DEVICE, AND A METHOD FOR THE GENERATIVE PRODUCTION OF A THREE-DIMENSIONAL OBJECT
(FR) CHAMBRE AMOVIBLE POUR UN DISPOSITIF ET UN PROCÉDÉ PERMETTANT LA FABRICATION ADDITIVE D'UN OBJET TRIDIMENSIONNEL
(DE) WECHSELKAMMER FÜR EINE VORRICHTUNG UND EIN VERFAHREN ZUM GENERATIVEN HERSTELLEN EINES DREIDIMENSIONALEN OBJEKTS
Abstract:
(EN) The invention relates to a changing chamber (10) for a device (1) for producing a three-dimensional object (2) by selectively solidifying construction material (24) in layers, preferably pulverulent construction material, at the cross-section of the object to be produced in locations corresponding to the respective layer, comprising a container (11, 12) with an upper edge and a lower edge, a wall (14), and a height-adjustable platform (21, 24) which is provided in the container. The wall of the container has a first sealing device (28) on the inner face of the wall, said sealing device adjoining the platform in a sealing position such that the first sealing device and the platform interact in order to close the container towards the lower edge.
(FR) L'invention concerne une chambre amovible (10) pour un dispositif (1) permettant la fabrication d'un objet tridimensionnel (2) par solidification sélective couche par couche d'un matériau de construction (24), de préférence un matériau de construction pulvérulent, en des emplacements correspondants à la section transversale de l'objet à fabriquer dans la couche respective. La chambre comporte un contenant (11, 12) pourvu d'un bord supérieur et d'un bord inférieur, d'une paroi (14) et d'une plateforme (21, 24) réglable en hauteur et située dans le contenant. La paroi du contenant présente sur sa face intérieure un premier dispositif d'étanchéité (28) qui se situe dans le prolongement de la plateforme dans une position d'étanchéité, de sorte que le premier dispositif d'étanchéité et la plateforme coopèrent pour fermer le contenant en direction du bord inférieur.
(DE) Eine Wechselkammer (10) für eine Vorrichtung (1) zum Herstellen eines dreidimensionalen Objekts (2) durch selektives schichtweises Verfestigen von Aufbaumaterial (24), vorzugsweise pulverförmigem Aufbaumaterial, an dem Querschnitt des herzustellenden Objekts in der jeweiligen Schicht entsprechenden Stellen, umfasst einen Behälter (11, 12) mit einem oberen Rand und einem unteren Rand, einer Wandung (14) und einer in dem Behälter vorgesehenen höhenverstellbaren Plattform (21, 24), wobei die Wandung des Behälters an ihrer Innenseite eine erste Dichteinrichtung (28) aufweist, die an die Plattform in einer Abdichtposition so anschließt, dass die erste Dichteinrichtung und die Plattform zum Verschließen des Behälters zum unteren Rand hin zusammenwirken.
