Zusammenfassung:	A drum for storing and processing build material powder includes a cylindrical body having a plurality of circumferential rings and a plurality of internal baffles. The first end of the cylindrical body is sealed by a first cap that is tapered to an orifice. The second end of the cylindrical body is sealed by a second cap. A gas inlet configured to receive an inflow of an inert gas and a gas outlet configured to exhaust used gas from an interior of the drum. Un tambour destiné à stocker et traiter une poudre de matériau de construction comprend un corps cylindrique ayant une pluralité d'anneaux circonférentiels et une pluralité de déflecteurs internes. La première extrémité du corps cylindrique est scellée par un premier capuchon qui s'effile en direction d'un orifice. La seconde extrémité du corps cylindrique est fermée de manière étanche par un second capuchon. Une entrée de gaz est conçue pour recevoir un flux entrant d'un gaz inerte et une sortie de gaz est conçue pour évacuer le gaz utilisé depuis l'intérieur du tambour.
