METHOD FOR PRODUCING AN INORGANIC FILTRATION MEDIUM THROUGH INTERMESHING AND OBTAINED MEMBRANE

The invention relates to a method for producing a porous monolithic inorganic medium (1) using a 3D printing machine comprising at least one extruder head (6) mounted so as to be moveable in space, the method consisting in: - driving the extruder head along a numerical trajectory so that: * for a pa...

Zusammenfassung:	The invention relates to a method for producing a porous monolithic inorganic medium (1) using a 3D printing machine comprising at least one extruder head (6) mounted so as to be moveable in space, the method consisting in: - driving the extruder head along a numerical trajectory so that: * for a path with overlap, the material being deposited partially overlaps at least one edge of a previously deposited deposit of material by a portion of overlapping material within its thickness and whose thickness is strictly less than the nominal height (e) so as to avoid gaps between the rounded edges of the deposit of material currently being deposited and those of the previously deposited deposit of material; * for a path with intersection, the material currently being deposited intersects with at least one previously deposited deposit of material that completely overlaps with the previously deposited deposit of material by a portion of overlapping material within its thickness and whose thickness is strictly less than the nominal height (e).
