Abstract

L’invention concerne un procédé de fabrication d’un élément moulant (10) d’un moule de cuisson, ledit élément moulant étant fabriqué par un procédé de fabrication additif par dépôt de couches de poudre et fusion sélective des couches de poudre, l’élément moulant comprenant une surface intérieure moulante (12) et une surface extérieure (14) opposée à la surface intérieure moulante, et l’élément moulant comprenant au moins un évent (20) permettant un passage d’air entre la surface intérieure moulante et la surface extérieure de l’élément moulant, le procédé de fabrication étant caractérisé en ce qu’il comprend les étapes suivantes :a) fabrication additive de l’élément moulant et d’au moins une zone poreuse dans cet élément moulant, la zone poreuse étant fabriquée de manière à présenter une densité de matière inférieure à la densité de matière de l’élément moulant en-dehors de cette zone poreuse, etb) réalisation par un procédé d’enlèvement de matière d’au moins un évent (20) dans la zone poreuse.
