Abstract
The present invention relates to a membrane and a method for manufacturing a membrane for filtering a fluid, said membrane comprising: a substrate having a three-dimensional structure and consisting of an one-piece ceramic porous body; and at least one separating filtering layer having a porosity that is lower than that of the substrate, in which the three-dimensional structure of the substrate is produced by forming elemental layers that are stacked and connected in series with one another, by repeating steps: a) depositing a continuous bed of powder at least partially consisting of a powder intended for forming the ceramic porous body; b) locally consolidating, part of the deposited material such as to create the elemental layer, and simultaneously linking the elemental layer thus formed with the preceding layer such as to gradually grow the desired three-dimensional shape.
