Abstract (en)

[origin: WO2021079057A1] The invention relates to a particle separation device for selective additive manufacture and to a selective additive manufacturing apparatus. The particles are contained in a gaseous stream. The device comprises a dry-type pressurized-air separator (101), said dry-type pressurized-air separator comprising a separating turbine of which a rotary speed is adjustable. The dry-type pressurized-air separator selects the particles contained in the gaseous stream according to a particle size dependent on the rotary speed of the separating turbine. The device further comprises a device (102) for extracting particles contained in the gaseous stream. Fluidic communication between the dry-type pressurized-air separator and the extraction device is such that a gaseous stream exiting the dry-type pressurized-air separator circulates in the extraction device and that the gaseous stream exiting the extraction device circulates in the dry-type pressurized-air separator. The device further comprises a device (103) for circulating the gaseous stream between the dry-type pressurized-air separator and the extraction device.
