Abstract

Machine de fabrication additive avec système d’écoulement gazeux La machine de fabrication additive (1) selon l’invention comprend un racleur (4) disposé sur un support (3), le racleur (4) se déplaçant entre une position de départ et une position d’arrivée sur ledit support (3), elle est caractérisée en ce que le racleur (4) comprend au moins une sortie de gaz (46) orientée vers le support (3) et vers l’arrière lors de son déplacement de la position de départ à la position d’arrivée. On peut ainsi créer un flux laminaire supplémentaire contrôlé de gaz au plus proche de la zone de fusion, ce qui permet de maitriser les écoulements gazeux et de limiter la génération de défaut dans la fabrication.
