Abstract: The invention relates to a method for producing a multi-capillary lining comprising a plurality of channels suitable for convection of a fluid between an inlet face and an outlet face of said lining, said method comprising the steps of: —providing at least one preform (1) suitable for forming, after ablation, a capillary channel (3) of the lining; —assembling said preforms into a bundle; —coating each preform (1) with a plurality of porous layers (2) by depositing alternating layers of a polyelectrolyte and nanoparticles or colloidal nanoparticles or by depositing alternating layers of said nanoparticles and a polymer glue; —bonding the coated preforms to form a porous monolith; and—ablating the preforms to form the channels in said porous monolith.

Abstract: The invention relates to a method for manufacturing a multicapillary packing for an exchange of material including the formation, by a 3D printing method, of a monolith having a porous mass through which a plurality of parallel channels passes, opening on an inlet face and an outlet face of the packing, the 3D printing method being chosen among: selective laser sintering, molten wire deposition, stereolithography, binder spraying and spraying of material, the porous mass being suitable for allowing the diffusion of material to be exchanged between the channels.
