    Abstract: A device for separating particles contained in a gas stream for selective additive manufacturing and a selective additive manufacturing apparatus are disclosed. The device comprises at least one dry-type aeraulic separator comprising a separating turbine, a speed of rotation of which is variable. The dry-type aeraulic separator selects the particles contained in the gas stream according to a particle size depending on the speed of rotation of the separating turbine. The device also comprises a device for extracting the particles. The dry-type aeraulic separator and the extraction device are in fluidic communication such that a gas stream exiting the dry-type aeraulic separator circulates through the extraction device and such that the gas stream exiting the extraction device circulates through the dry-type aeraulic separator. The device also comprises a device for circulating the gas stream between the dry-type aeraulic separator and the extraction device.

    Abstract: An additive manufacturing machine comprises a work surface, a build sleeve (44), and a build platform (46) moving translationally between a raised position and a lowered position under the effect of an actuator (48), the platform being connected to the actuator by a support (50). The build sleeve (44) comprises a slot (66) allowing the support (50) to pass through the build sleeve to connect the platform to the actuator when the build platform translates from its raised position to its lowered position, a closing-off element (68) allowing a slot (66) to be closed off progressively as the platform effects its translational movement inside the sleeve from its raised position to its lowered position, a closing-off element (68) being a tape (70), and the upper end (U70) of a closing-off tape being fixed to the upper edge of the build sleeve or to the work surface.

    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.
