A method of producing an open, porous structure having an outer surface defining a shape having a bulk volume and having interconnecting openings extending throughout said volume and opening through said surface, and products resulting from the method. The method comprises preparing a viscous mixtur
A method of producing an open, porous structure having an outer surface defining a shape having a bulk volume and having interconnecting openings extending throughout said volume and opening through said surface, and products resulting from the method. The method comprises preparing a viscous mixture comprising a sinterable powder dispersed in a sol of a polymer in a primary solvent, replacing the primary solvent with a secondary liquid in which the polymer is insoluble to produce a gel comprising an open polymeric network having the sinterable powder arranged therein, removing the secondary liquid from the gel; removing the polymer network, and sintering the sinterable powder to form the open, porous structure. Also disclosed are shaped, porous products resulting from methods of the invention.
