Abstract: A machine (10) for additive manufacturing by powder bed deposition comprises a work surface (12), a device (16) for selective consolidation, a device (18) for extracting the fumes, the selective consolidation device emitting at least two beams (F1, F2) of energy or heat. The work surface is divided into at least two work zones (Z1, Z2) adjacent to one another, and a first beam (F1) consolidates the powder in a first work zone (Z1) and a second beam (F2) consolidates the powder in a second work zone (Z2). The fume extraction device (18) comprises at least one central gas suction and/or gas blowing manifold (40) which is mounted to be translationally movable above an overlap zone (ZR) of the different adjacent work zones, and two side gas suction and/or gas blowing manifolds (42, 44) which are fixedly mounted and arranged on either side of the work surface, whcrcin the central manifold (40) extends at least over a maximum dimension of the work surface.

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 additive manufacturing machine (10) comprises a working plane (18) comprising a working zone (20) allowing an overlay of different layers of powder to be received, and a powder dispensing device (32) comprising a powder intake (36) allowing powder to be delivered on top of the working plane. The powder dispensing device (32) comprises a tank (44) of powder mounted to move above the working plane (18) and that can be displaced to under the powder intake (36), the bottom part (45) of the tank (44) comprises a powder dispensing point (P1), and the powder dispensing device (32) comprises a control device (48) controlling the flow of powder via the powder dispensing point during a displacement of the tank. The tank (44) is mounted on a weighing sensor (68).
