Title (EN) SUCTION DEVICE FOR ADDITIVE PRODUCTION
(FR) DISPOSITIF D'ASPIRATION DESTINÉ À LA FABRICATION ADDITIVE
(DE) ABSAUGVORRICHTUNG FÜR DIE ADDITIVE FERTIGUNG
Abstract:
(EN) The invention relates to a device (100) for guiding a protective gas (SG) over a powder bed (PB) for the purpose of additive production. The device comprises a gas inlet (14) for introducing the protective gas (SG) to the powder bed (PB) and a stationary gas outlet (12) for removing the protective gas (SG), wherein the device (100) is furthermore designed to guide the protective gas (SG) over the powder bed (PB) in a laminar manner, and wherein the device (100) furthermore has an outlet opening (10), configured parallel to a powder bed plane, for suctioning the protective gas out of a construction chamber (BR) during additive production of a component (3). The invention furthermore relates to a method for guiding a protective gas flow.
(FR) L'invention concerne un dispositif (100) destiné à guider un gaz protecteur (SG) au-dessus d'un lit de poudre (PB) pour la fabrication additive. Le dispositif (100) comprend une entrée de gaz (14), destinée à introduire le gaz protecteur (SG) sur le lit de poudre (PB), et une sortie de gaz stationnaire (12), destinée à évacuer le gaz protecteur (SG), le dispositif (100) étant en outre conçu pour guider le gaz protecteur (SG) de façon laminaire au-dessus du lit de poudre (PB), et le dispositif (100) comportant en outre un orifice de sortie (10) agencé mobile parallèlement à un plan de lit de poudre, qui est destiné à aspirer le gaz protecteur hors d'un espace de montage (BR) pendant la fabrication additive d'une pièce (3). L’invention concerne en outre un procédé destiné à guider un flux de gaz protecteur.
(DE) Es wird eine Vorrichtung (100) zum Führen eines Schutzgases (SG) über ein Pulverbett (PB) für die additive Herstellung angegeben. Die Vorrichtung umfasst einen Gaseinlass (14) zum Einbringen des Schutzgases (SG) auf das Pulverbett (PB) und einen stationären Gasauslass (12) zum Entfernen des Schutzgases (SG), wobei die Vorrichtung (100) weiterhin ausgebildet ist, das Schutzgas (SG) laminar über das Pulverbett (PB) zu führen, und wobei die Vorrichtung (100) weiterhin zum Absaugen des Schutzgases aus einem Bauraum (BR) während der additiven Herstellung eines Bauteils (3) eine parallel zu einer Pulverbettebene beweglich eingerichtete Auslassöffnung (10) aufweist. Weiterhin wird ein Verfahren zum Führen einer Schutzgasströmung angegeben.
