FIELD: filtration of fluids.
SUBSTANCE: invention relates to a method for manufacturing a porous monolithic inorganic substrate, a method for producing a membrane for tangential filtration, a porous monolithic inorganic substrate, and a membrane for tangential filtration. A method for manufacturing at least one porous monolithic inorganic substrate having a porosity of 10% to 60% and an average pore diameter in the range from 0.5 mcm to 50 mcm includes preparing an inorganic composition containing a powdered solid inorganic phase, supplying the composition into the extrusion head of a 3D printing machine to build a raw 3D structure that can be manipulated. The resulting structure is then placed in a heat treatment oven for sintering at a temperature of 0.5 to 1 times the melting temperature of at least one material forming the inorganic phase.
EFFECT: mechanically strong porous substrate.
