In one example, a group of interchangeable supply modules to hold powdered build material for additive manufacturing. Each supply module in the group includes an exterior sized and shaped to fit into a mixer; an interior defining a non-circular mixing chamber, and an outlet through which powdered build material may leave the mixing chamber. Dans un exemple, un groupe de modules d'alimentation interchangeables permet de contenir un matériau de construction en poudre pour la fabrication additive. Chaque module d'alimentation du groupe comprend un extérieur dimensionné et formé pour s'insérer dans un mélangeur ; un intérieur définissant une chambre de mélange non circulaire, et une sortie à travers laquelle le matériau de construction en poudre peut quitter la chambre de mélange.
