Abstract
A powder bed fusion additive manufacturing machine (10) comprises a working area (20) able to receive a superposition of different layers of powder, a device (30) for depositing a layer of powder onto the working area and a consolidation source (40) 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 (32) 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 (68) 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.
