Abstract

Procédé de fonctionnement d’un système de fusion laser sur lit de poudre lors duquel au moins une couche de poudre est étalée à l’aide d’un racleur (17) et au moins un son émis par ledit système est capté lors de l’étalement, dans lequel ledit son capté (25) est comparé à d’autres sons d’une base de données (27) comportant des sons normaux de référence émis lors d’un fonctionnement normal dudit système et des sons anormaux de référence émis lors d’un dysfonctionnement de l’étalement de la couche de poudre, de façon à déterminer si ledit son correspond à un son normal ou à un son anormal Figure de l’abrégé : Figure 2Method of operating a laser powder bed fusion system in which at least one layer of powder is spread using a scraper (17) and at least one sound emitted by said system is captured during the spreading, in which said captured sound (25) is compared to other sounds from a database (27) comprising normal reference sounds emitted during normal operation of said system and abnormal reference sounds emitted during a malfunction in the spreading of the powder layer, so as to determine whether said sound corresponds to a normal sound or an abnormal sound Abstract figure: Figure 2
