Abstract
The present invention relates to a method for manufacturing at least one monolithic inorganic porous support (1) having a porosity comprised between 10% and 60% and an average pore diameter ranging from 0.5 μm to 50 μm, using a 3D printer type machine (I) to build, in accordance with a 3D digital model, a manipulable three-dimensional green structure (2) intended to form, after sintering, the monolithic inorganic porous support(s) (1).
