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.The invention relates to a method of cleaning a part manufactured by an additive manufacturing process using an additive manufacturing powder, this part comprising at least one cavity capable of containing a powder agglomerate at the end of the additive manufacturing process, and this cavity comprising at least one opening, the cleaning process being characterized in that it uses a cleaning product which can take at least two liquid and gaseous states and change from the liquid state to the gaseous state, and in that that it comprises at least the following steps: a) immersing the part in the cleaning product in the liquid state so that the cleaning product at least partially fills the cavity, b) sealing each opening of the cavity with using a stopper, c) bringing at least part of the cleaning product contained in the cavity to its gaseous state so as to increase the pressure of the cleaning product in the cavity.
