Beschreibung
Zusammenfassung:	According to the present invention a method for generating a three-dimensional workpiece is provided, wherein the method comprises the following steps: producing a workpiece via additive manufacturing process, wherein Nitrogen is used as a protective/shielding gas during the additive manufacturing process, and wherein Nitrogen is trapped in pores of the material of the work piece, treating the workpiece with a hot isostatic pressing process, wherein Nitrogen diffuses out of the material of the component so that a high density part is achieved. La présente invention concerne un procédé de génération d'une pièce de fabrication tridimensionnelle, le procédé comprenant les étapes suivantes : produire une pièce de fabrication par l'intermédiaire d'un processus de fabrication additive, de l'azote étant utilisé comme gaz protecteur/de blindage pendant le processus de fabrication additive, et de l'azote étant piégé dans des pores du matériau de la pièce de fabrication, traiter la pièce de fabrication avec un processus de pressage isostatique à chaud, de l'azote se diffusant hors du matériau du composant de sorte qu'une pièce à haute densité est obtenue.
