1. A powder bed fusion additive manufacturing machine comprising:
a working area configured 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 configured to selectively consolidate each layer of powder deposited onto the working area,
wherein the device for depositing the layer of powder comprises:
a powder reservoir configured to be positioned above the working area;
a powder distribution opening provided in a bottom part of the powder reservoir and equipped with a sieve;
a vibrating device configured to subject the powder reservoir to vibrations, and
wherein the powder reservoir is mounted on a weighing sensor, and
wherein, with the sieve being mounted on the powder reservoir via a ring having a shoulder to hold the sieve, a cross-section of the sieve-holding shoulder decreases progressively in a direction away from the sieve.
