description	Le présent document concerne un procédé de fabrication d'une bobine d'un filament (1), ledit procédé comprenant les étapes : extruder (2) un mélange de liants cristallins ou semi-cristallins et d'au moins 90% en masse ou 60% en volume de poudre métallique ou céramique de sorte à obtenir un filament ;réaliser une trempe (3) dudit filament à une température de trempe déterminée pour abaisser entre 5% et 15% un taux de cristallinité dans lesdits liants ;enrouler ledit filament (4), autour de la bobine, à une température comprise entre 10°C et une température inférieure à la température de trempe. Figure de l'abrégé : Figure 4 The present invention relates to a method for producing (1) a reel for a filament, said method comprising the steps of: - extruding (2) a blend of crystalline or semicrystalline binders and at least 90% by weight or 60% by volume of metal or ceramic powder so as to obtain a filament; - quenching (3) said filament at a predetermined quenching temperature in order to reduce, by between 5% and 15%, a degree of crystallinity in said binders; - winding (4) said filament around the reel at a temperature of between 10°C and a temperature below the quenching temperature.
