Beschreibung
Zusammenfassung:	A method of forming a mold used to manufacture downhole tools includes depositing successive layers of a material mixture and an adhesive using an automated layering device according to a computer aided pattern, the material mixture including a first composition and a second composition, the first composition having at least a different shape, size, or chemical composition than the second composition, at least one of the first composition or the second composition being granulated. L'invention concerne un procédé de formation d'un moule utilisé pour fabriquer des outils de fond de trou, comprenant le dépôt de couches successives d'un mélange de matériaux et d'un adhésif à l'aide d'un dispositif de superposition de couches automatisé selon un motif assisté par ordinateur, le mélange de matériaux comprenant une première composition et une seconde composition, la première composition ayant au moins une forme, taille ou composition chimique différente de celle de la seconde composition et la première composition et/ou la seconde composition étant granulées.
