A powder bed fusion additive manufacturing machine () comprises a working area () able to receive a superposition of different layers of powder, a device () for depositing a layer of powder onto the working area and a consolidation source () used to selectively consolidate each layer of powder deposited onto the working area, the device for depositing a layer of powder comprising a powder reservoir () able to be positioned above the working area, and a powder distribution opening being provided in the bottom part of the reservoir, the device for depositing a layer of powder comprising a vibrating device () able to subject the reservoir to vibrations, and the powder distribution opening of the reservoir being equipped with a sieve. The reservoir is mounted on a weighing sensor.

Additive manufacturing machine with powder dispensing by sieving

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

Additive manufacturing machine with movable, controlled powder dispensing

An additive manufacturing machine () comprises at least one movable powder reception surface () capable of being displaced in proximity to a manufacturing zone (), a powder spreading device (), and a device () for distributing powder on the movable reception surface. The powder distribution device comprises a buffer tank () linked to a powder supply () and a distribution duct () linking the buffer tank to a powder distribution point (P) situated above the movable reception surface, and the distribution duct () is mounted on a vibrating device making it possible to vibrate the distribution duct so as to generate a continuous flow of powder in the distribution duct and from the buffer tank to the powder distribution point.
