Abstract

Procédé de fusion sélective sur lit de poudre d’un alliage à solidification dirigée au moyen d’un faisceau laser, le faisceau laser se déplaçant selon une première direction de balayage dans une couche n et une deuxième direction de balayage dans une couche n+1, la deuxième direction de balayage étant perpendiculaire à la première direction de balayage, dans lequel θ3-θ1 < 90°, θ1 et θ3 étant mesurés dans un plan perpendiculaire à la première direction de balayage, θ1 étant la valeur maximale de l’angle formé par le gradient thermique et la direction verticale d’un premier cordon m de la couche n (12), à l’intersection du premier cordon m et d’un deuxième cordon m+1, et θ3 étant la valeur maximale de l’angle formé par le gradient thermique et la direction verticale du premier cordon m de la couche n (12) avec un cordon de la couche n+1 et dans lequel une vitesse de balayage du faisceau laser est supérieure ou égale à 400 mm/s.
