Title
(EN) IMAGING DEVICES FOR USE WITH ADDITIVE MANUFACTURING SYSTEMS AND METHODS OF MONITORING AND INSPECTING ADDITIVE MANUFACTURING COMPONENTS
(FR) DISPOSITIFS D'IMAGERIE DESTINÉS À ÊTRE UTILISÉS AVEC DES SYSTÈMES DE FABRICATION ADDITIVE ET PROCÉDÉS DE SURVEILLANCE ET D'INSPECTION DE COMPOSANTS DE FABRICATION ADDITIVE
Abstract
(EN)
An additive manufacturing system includes at least one imaging device configured to direct electromagnetic radiation towards a build layer of a component positioned within a powder bed of the additive manufacturing system. The additive manufacturing system also includes at least one detector configured to detect the electromagnetic radiation that reflects from the build layer.
(FR)
Système de fabrication additive comprenant au moins un dispositif d'imagerie conçu pour diriger un rayonnement électromagnétique vers une couche de construction d'un composant positionné dans un lit de poudre du système de fabrication additive. Le système de fabrication additive comprend également au moins un détecteur conçu pour détecter le rayonnement électromagnétique qui réfléchit à partir de la couche de construction.
