Abstract
(EN)
The invention relates to a method for manufacturing at least one porous single-piece inorganic support (1) having a porosity of between 10% and 60% and an average pore diameter ranging from 0.5 μm to 50 μm, using a 3D printer-type machine (I) designed to build following a digital 3D model, and a manipulable three-dimensional green structure (2) designed to form, after sintering, the porous single-piece inorganic support(s) (1).
(FR)
La présente invention concerne un procédé de fabrication d'au moins un support inorganique monolithique poreux (1) présentant une porosité comprise entre 10% et 60% et un diamètre moyen de pores allant de 0,5 pm à 50 pm, à l'aide d'une machine de type imprimante 3D (I) pour bâtir selon un modèle 3D numérique, une structure tridimensionnelle crue manipulable (2) destinée à former après frittage le ou les supports inorganiques poreux monolithiques (1).
