METHOD FOR MANUFACTURING OBJECTS USING POWDER PRODUCTS

A method for manufacturing a three-dimensional part. The method includes: performing partial densification processing on loose machining powder, to form a densified and sealed enclosure, where there is still loose machining powder accommodated inside the enclosure; and performing overall densificati...

Zusammenfassung:	A method for manufacturing a three-dimensional part. The method includes: performing partial densification processing on loose machining powder, to form a densified and sealed enclosure, where there is still loose machining powder accommodated inside the enclosure; and performing overall densification processing on the enclosure and the machining powder inside the enclosure, so as to implement metallurgical bonding between the machining powder inside the enclosure and the enclosure during the densification, thereby forming a target three-dimensional part. Une méthode de fabrication dune pièce tridimensionnelle. La méthode comprend : la réalisation du processus de densification partielle sur une poudre dusinage en vrac pour former une enceinte densifiée et étanche, dans laquelle se trouve encore de la poudre dusinage en vrac logée à lintérieur de lenceinte; et la réalisation dun processus de densification partielle général sur lenceinte et la poudre dusinage à lintérieur de lenceinte, pour mettre en place une liaison métallurgique entre la poudre dusinage à lintérieur de lenceinte et lenceinte pendant la densification, formant ainsi une pièce tridimensionnelle cible.
