Abstract

DISPOSITIF ET MÉTHODE DE CARTOGRAPHIE DE L'ÉCOULEMENT D'UN GAZ DANS UNE MACHINE DE FABRICATION ADDITIVE Un aspect de l’invention concerne un dispositif de cartographie (100) de la vitesse d'un gaz au niveau d’un plan de travail d'une machine de fabrication additive, caractérisé en ce qu'il comprend : un outillage (200) comprenant une surface plane (210), destiné à être placé dans la machine de fabrication additive de telle sorte que la surface plane (210) coïncide avec le plan de travail de la machine de fabrication additive, la surface plane (210) comprenant une pluralité d'ouvertures (220) ;un anémomètre (300) comprenant un corps et une extrémité sensible, le corps de l'anémomètre étant inséré dans l'une des ouvertures (220) de la surface plane (210), l'extrémité sensible dépassant de la surface plane (210). Figure à publier avec l’abrégé : Figure 1DEVICE AND METHOD FOR MAPPING THE FLOW OF A GAS IN AN ADDITIVE MANUFACTURING MACHINE One aspect of the invention relates to a device for mapping (100) the speed of a gas at the level of a work surface of an additive manufacturing machine, characterized in that it comprises: tooling (200) comprising a flat surface (210), intended to be placed in the additive manufacturing machine such that the flat surface (210) coincides with the work surface of the additive manufacturing machine, the flat surface (210) comprising a plurality of openings (220); an anemometer (300) comprising a body and a sensitive end, the body of the anemometer being inserted into the one of the openings (220) of the flat surface (210), the sensitive end protruding from the flat surface (210). Figure to be published with the abstract: Figure 1
