Abstract
L’invention concerne un procédé de nettoyage d’une pièce fabriquée par un procédé de fabrication additive utilisant une poudre de fabrication additive, cette pièce comprenant au moins une cavité susceptible de contenir un agglomérat de poudre à l’issue du procédé de fabrication additive, et cette cavité comprenant au moins une ouverture, le procédé de nettoyage étant caractérisé en ce qu’il utilise un produit de nettoyage pouvant prendre au moins deux états liquide et gazeux et passer de l’état liquide à l’état gazeux, et en ce qu’il comprend au moins les étapes suivantes :a) plonger la pièce dans le produit de nettoyage à l’état liquide de manière à ce que le produit de nettoyage remplisse au moins partiellement la cavité,b) obturer chaque ouverture de la cavité à l’aide d’un bouchon,c) amener au moins une partie du produit de nettoyage contenu dans la cavité vers son état gazeux de manière à augmenter la pression du produit de nettoyage dans la cavité.
