Additive manufacturing of metals — Feedstock materials — Correlating of rotating drum measurement with powder spreadability in PBF-LB machines

This document provides an example of the relation between the characterization of certain macroscopic properties of metallic powders and their spreadability in an PBF-LB/M AM machines. This relation is based on a new technique combining measurements inside a PBF-LB/M machine and image processing developed to quantify the homogeneity of the powder bed layers during spreading. In this document, the flowability of five metal powders are investigated with an automated rotating drum method, whose dynamic cohesive index measurement is shown to establish a correlation with the spreadability of the powder during the layer deposition operation. Furthemore, the particule size distribution (PSD) and morphology of each powder is characterized before testing by static image analysis method (according to ISO 13322-1). The general principle of the method is described in Figure 1.

Fabrication additive de métaux — Matières premières — Corrélation de la mesure du tambour rotatif avec la capacité d'étalement de la poudre dans les machines PBF-LB

Le présent document fournit un exemple de la relation entre la caractérisation de certaines propriétés macroscopiques des poudres métalliques et leur étalabilité dans les machines PBF-LB/M de FA. Cette relation repose sur une nouvelle technique combinant les mesurages à l’intérieur de la machine PBF-LB/M et le traitement d’image, développée pour quantifier l’homogénéité des couches du lit de poudre pendant l’étalement. Dans le présent document, la coulabilité de cinq poudres métalliques est étudiée en utilisant une méthode automatisée avec un tambour rotatif, dont le mesurage de l’indice de cohésion dynamique est représenté pour établir une corrélation avec l’étalabilité de la poudre pendant l’opération de dépôt des couches. De plus, la distribution granulométrique (PSD) et la morphologie de chaque poudre sont caractérisées avant l’essai par une méthode d’analyse d’image statique (conformément à l’ISO 13322-1). Le principe général de la méthode est décrit à la Figure 1.
