Abstract: An additive-manufacturing facility and a method for managing a powder transported to and from additive-manufacturing machines of the facility are provided. According to the method, a volume of feedstock powder is stored, and the machines are automatically fed with powder from the volume of feedstock powder. For each machine, the powder fed to the machine undergoes at least one layering operation during an additive-manufacturing cycle, and excess powder in the layering operation is moved away and conveyed from the machine to the volume of feedstock powder. For each machine, recovered powder, which is derived from cleaning rough components produced by the machine, is reintroduced into the volume of feedstock powder. A same collection circuit is used to convey the excess powder and the recovered powder to the volume of feedstock powder.
