A method of producing reticular structures, particularly metallic reticular structures, as well as a device suitable for the production thereof. The method and device enable continuous and/or automated production of such structures, and particularly, large-scale automated production of large-dimensioned reticular structures. A reticulated foam pre-structure is placed into a first container and infiltrated with a refractory material. After solidification, the mold formed by the refractory material is removed from the first container and the foam pre-structure stripped from the mold. The mold is then pre-heated and placed into a second container and infiltrated with a molten substance that forms the reticular structure when solidified. The filled mold may be covered with a solid jacket as a means of controlling the rate and progression of solidification of the molten substance to form a fine-grained, bubble-free structure.

1. A method of producing a reticular structure, said method comprising the steps of:a) placing a reticulated foam pre-structure into a first container having a lid; b) infiltrating said foam pre-structure with a refractory mold material; c) solidifying said refractory material to form a refractory mold; d) withdrawing said refractory mold along with said foam pre-structure from said first container; e) removing said foam pre-structure from said refractory mold; f) placing said refractory mold into a second container having at least one opening for pouring in a molten substance and at least one wall, wherein said second container is greater in size than said refractory mold so as to leave a gap between said refractory mold and said at least one wall; g) infiltrating said refractory mold with said molten substance to form a reticular structure; h) pouring a jacket material over said refractory mold so as to fill said gap with said jacket material to form a plate; i) cooling said reticular structure by maintaining a temperature of said second container, and particularly of said at least one wall, that is lower than a temperature of said molten substance so as to draw heat from said reticular structure into said second container, and particularly through said plate; and j) after said molten substance has solidified, withdrawing said reticular structure from said second container and removing said refractory mold from said reticular structure. 2. The method of producing a reticular structure according to claim 1, wherein, after said step of withdrawing said refractory mold from said first container, said foam pre-structure protrudes from said refractory mold.3. The method of producing a reticular structure according to claim 1, wherein said foam pre-structure has a surface and wherein, subsequent to step a), said method includes a step of modifying said surface by roughening.4. The method of producing a reticular structure according to claim 1, wherein said foam pre-structure has a surface and wherein, subsequent to step a), said method includes a step of modifying said surface by texturing.5. The method of producing a reticular structure according to claim 1, wherein said reticular structure has a structure surface and wherein, subsequent to step h), said method includes a step of modifying said structure surface by applying a coating to said structure surface.6. The method of claim 1, wherein said reticular structure is a metallic reticular structure and said molten substance is a molten metallic substance comprising materials from a group consisting of metals, metal alloys, ceramics and cermet.7. The method of claim 1, wherein said foam pre-structure is a polyurethane foam.8. The method of claim 1, wherein said refractory mold material comprises a gypsum plaster suspension.9. The method of claim 1, wherein said first container is made of a refractory material.10. The method of claim 1, wherein said second container is made of a heat-resistant material.
