Beschreibung
Zusammenfassung:	The present invention relates to a method for the recovery and regeneration of metal powders in EBM (Electron Beam Melting) applications, comprising: recovering of metal powders inside a cleaning chamber (2) of three-dimensional objects obtained by means of EBM sintering of said metal powders; treating the metal powders by mixing thoroughly with supplied metal powders (ELI) with a predetermined oxygen content of less than 0.12% by weight; obtaining regenerated metal powders in which the oxygen content is restored to a value below a predetermined threshold.
