Title
(EN) METHOD FOR MATERIAL ADDITIVE MANUFACTURING OF AN INORGANIC FILTER SUPPORT AND RESULTING MEMBRANE
(FR) PROCEDE DE FABRICATION PAR ADDITION DE MATIERE D'UN SUPPORT INORGANIQUE DE FILTRATION ET MEMBRANE OBTENUE
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).
