| description | The invention relates to a device for the additive manufacturing of workpieces under protective gas, which device is provided with a manufacturing chamber designed as a pressure chamber, said manufacturing chamber being fluidically connected to a pressure container via a gas extraction line, which is provided with a vacuum pump, and via a gas return line. After the manufacturing of a first workpiece, the protective gas present in the manufacturing chamber is evacuated, temporarily stored in the pressure container and, prior to the manufacturing of a second workpiece, is introduced into the manufacturing chamber.
L'invention concerne un dispositif de fabrication additive de pièces sous gaz protecteur, lequel dispositif est pourvu d'une chambre de fabrication réalisée sous la forme d'une chambre sous pression, ladite chambre de fabrication étant en communication fluidique avec un récipient sous pression par l'intermédiaire d'une conduite d'extraction de gaz qui est pourvue d'une pompe à vide, et par l'intermédiaire d'une conduite de retour de gaz. Après la fabrication d'une première pièce, le gaz protecteur présent dans la chambre de fabrication est évacué, stocké temporairement dans le récipient sous pression et introduit, avant la fabrication d'une seconde pièce, dans la chambre de fabrication. |
