Zusammenfassung:	A processing machine (10) for building an object (11) from powder (12) includes a build platform (26A); a powder supply assembly (18) that deposits the powder (12) onto the build platform (26A) to form a powder layer (13); and an energy system (22) that directs an energy beam (22D) at a portion of the powder (12) on the build platform (26A) to form a portion of the object (11). The powder supply assembly (18) can include (i) a powder container (640A) that retains the powder (12); (ii) a supply outlet (639) positioned over the build platform (26A); and (ii) a flow control assembly (642) that selectively controls the flow of the powder (12) from the supply outlet (639). L'invention concerne une machine de traitement (10) pour construire un objet (11) à partir de poudre (12), comprenant une plateforme de construction (26A); un ensemble d'alimentation en poudre (18) qui dépose la poudre (12) sur la plateforme de construction (26A) pour former une couche de poudre (13); et un système d'énergie (22) qui dirige un faisceau d'énergie (22D) au niveau d'une partie de la poudre (12) sur la plateforme de construction (26A) pour former une partie de l'objet (11). L'ensemble d'alimentation en poudre (18) peut comprendre (i) un réservoir à poudre (640A) qui contient la poudre (12); (ii) une sortie d'alimentation (639) positionnée au-dessus de la plateforme de construction (26A); et (ii) un ensemble de réglage de débit (642) qui règle sélectivement le débit de la poudre (12) depuis la sortie d'alimentation (639).
