Abstract: An inertable container (10) for transporting an additive manufacturing powder comprises an inertable volume (12) and a main opening (14) granting access to the inside of this inertable volume, the inertable volume (12) comprising an upper portion (16) and a lower portion (18), the main opening (14) being located in the lower portion (18) of the inertable volume, and the section (S12) of the inertable volume (12) increasing gradually over at least part of the height (H10) of the container (10) and from the lower portion (18) towards the upper portion (16) of the inertable volume. The main opening is equipped with a passive half-valve (20) allowing this main opening (14) to be closed in such a way as to be sealed in an airtight and humidity-proof manner. The container comprises at least two inerting tappings.

Abstract: A supply module (2) for supplying additive manufacturing powder comprises: a main hopper (29) for storing additive manufacturing powder, the main hopper (29) being designed to be connected to a manufacturing module (4) configured to additively manufacture an object from the powder; an inlet (211) of the supply module (2) designed to be connected to the manufacturing module (4) and to receive powder located in the manufacturing module (4); a glovebox (25) being able to be closed in a sealed manner; a provisioning circuit configured to transfer powder located in the glovebox (25) to the main hopper (29); and a circulation system designed to set powder in motion according to a circulation loop closed on itself, the circulation system comprising a suction system (21) designed to evacuate gas present in the circulation loop, the circulation loop passing through the main hopper (29) and the suction system (21).

Abstract: The disclosure relates in particular to a machine for additive manufacturing by sintering or melting powder using an energy beam acting on a powder layer in a working zone, said machine comprising a device for layering said powder. The device is configured to distribute the powder that are able to travel over the working zone in order to distribute the powder in a layer having a final thickness suitable for additive manufacturing; transfer the powder to a distribution structure by gravity, and control the quantity of powder transferred to the distribution structure.
