Abstract:
A method of unclogging ducts in a part made by additive manufacturing, the ducts running from at least one well that opens out into the surface of the part, the method comprising the steps of: fabricating a guide with a body that is designed to fit in the well, the guide having internal channels that extend from a base of the guide that is accessible by a user to an outside wall of the body; cleaning the well and inserting the body of the guide in the well so that channels in the guide open out in register with inlets of ducts that are to be unclogged; and inserting a thin flexible tool, e.g. a metal cable, through the base of the guide into at least one channel therein and causing the tool to penetrate into the duct in register in the part so as to unclog it.
