1. A solid freeform fabrication method of creating a three-dimensional article built at least in part from scaffolding layers, the method comprising: providing a scaffolding material;providing a supporting material in a shape of a foamy layer; andcontacting the scaffolding material with the foamy layer to form at least one scaffolding layer and thereby creating the three dimensional article. 2. The method of claim 1, wherein the scaffolding material is deposited on a top outer surface of the foamy layer, inside the foamy layer or both. 3. The method of claim 1, wherein the supporting material comprises a foaming agent. 4. The method of claim 1, wherein the supporting material comprises a foaming agent and a crosslinking agent. 5. The method of claim 4, wherein the foaming agent is a member selected from the group consisting of anionic surfactants, cationic surfactants, amphoteric surfactants, non-ionic surfactants, hydrolyzed protein and fluorocarbon surfactants. 6. The method of claim 4, wherein the crosslinking agent is a member selected from the group consisting of calcium chloride, barium chloride, thrombin, sodium hydroxide and glutaraldehyde. 7. The method of claim 1, wherein the scaffolding material is a member selected from the group consisting of alginate, chitosan, collagen, fibrin, salts and derivatives thereof. 8. The method of claim 1, wherein the supporting material further comprises a biologically active agent. 9. The method of claim 8, wherein the biologically active agent is a member selected from the group consisting of cells, nucleic acids, proteins, and pharmacologically active agents. 10. The method of claim 1, wherein the supporting material further comprises at least one of a surface modifier or a sterilizing agent. 11. The method of claim 1, further comprising depositing the supporting material simultaneously with the scaffolding material such that the supporting material is retained within the three dimensional article. 12. The method of claim 11, wherein the supporting material comprises a foaming agent, a crosslinking agent and optionally a biologically active agent. 13. The method of claim 12, wherein the supporting material further comprises at least one of a surface modifier or a sterilizing agent. 14. The method of claim 1, wherein the foamy layer acts as a cooling media for the scaffolding material.
