Title (DE) VORRICHTUNG UND VERFAHREN ZUM HERSTELLEN EINES DREIDIMENSIONALEN OBJEKTS
(EN) DEVICE AND METHOD FOR PRODUCING A THREE-DIMENSIONAL OBJECT
(FR) DISPOSITIF ET PROCÉDÉ POUR PRODUIRE UN OBJET TRIDIMENSIONNEL
Abstract:
(DE) Vorrichtung (1) zum Herstellen eines dreidimensionalen Objekts (2) durch schichtweises Verfestigen von Aufbaumaterial (15) an den dem Querschnitt des herzustellenden Objekts (2) in einer jeweiligen Schicht entsprechenden Stellen mit einer Prozesskammer (3), in der das Objekt (2) durch selektives Verfestigen von Schichten eines Aufbaumaterials (15) in einem Baufeld (8) schichtweise aufzubauen ist, einer Gaszufuhreinrichtung (100) und einer Umluftfiltereinrichtung (32), wobei die Vorrichtung (1) eine Druckkonstanthalteeinrichtung, die ausgebildet ist, den Druck in der Prozesskammer (3) im Wesentlichen konstant zu halten, aufweist.
(EN) The invention relates to a device (1) for producing a three-dimensional object (2) by solidifying construction material (15) layer by layer at locations in the respective layer, which correspond to the cross-section of the object (2) to be produced, comprising a process chamber (3), in which the object (2) is to be constructed layer by layer by selectively solidifying layers of a construction material (15) in a construction field (8), a gas supply device (100) and a circulating air filter device (32), wherein the device (1) comprises a device for maintaining a pressure constant, which is designed to maintain the pressure in the process chamber (3) substantially constant.
(FR) L'invention concerne un dispositif (1) pour produire un objet tridimensionnel (2) par solidification, couche par couche, de matière de construction (15) aux emplacements correspondant à la section transversale de l'objet (2) à produire dans une couche respective, comprenant une chambre de traitement (3) dans laquelle l'objet (2) doit être construit, couche par couche, par solidification sélective de couches d'une matière de construction (15) dans une zone de construction (8), un dispositif d'alimentation en gaz (100) et un dispositif de filtrage d'air ambiant (32), ledit dispositif (1) comportant un système de maintien de pression constante conçu pour maintenir sensiblement constante la pression dans la chambre de traitement (3).
