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).
