A method of printing a three dimensional article comprising: selectively depositing layers of a fluid build material to form the three dimensional article on a substrate, wherein the build material comprises: an oligomeric curable material;a reactive component;a non-reactive component comprising one or more urethane waxes; andat least one diluent, wherein the reactive component comprises at least one chemical moiety that is polymerizable with a chemical moiety contained in the oligomeric curable material and/or the at least one diluent and wherein the reactive component is present in the build material as crystalline regions. 2. The method of claim 1, wherein the layers of the build material are deposited according to an image of the three dimensional article in a computer readable format. 3. The method of claim 1 further comprising supporting at least one of the layers of the build material with a support material. 4. The method of claim 1 further comprising curing the build material. 5. The method of claim 1, wherein the build material solidifies upon deposition. 6. The method of claim 1, wherein the build material remains substantially fluid upon deposition. 7. The method of claim 1, wherein the non-reactive component does not comprise a chemical moiety that is polymerizable with a chemical moiety contained in the oligomeric curable material or the at least one diluent. 8. The method of claim 1, wherein the build material further comprises one or more additives selected from the group consisting of photoinitiators, inhibitors, stabilizing agents, sensitizers, and combinations thereof. 9. The method of claim 1, wherein the oligomeric curable material is a urethane (meth)acrylate having a viscosity ranging from 10,000 cps to 300,000 cps. 10. The method of claim 1, wherein the oligomeric curable material and the reactive component each contain one or more acrylate or (meth)acrylate moieties. 11. The method of claim 1, wherein the reactive component comprises more than one chemical moiety that is polymerizable with a chemical moiety contained in the oligomeric curable material and/or the at least one diluent. 12. The method of claim 1, wherein the reactive component comprises at least one of the following: a urethane (meth)acrylate, a urea (meth)acrylate, and an isocyanurate (meth)acrylate. 13.

The method of claim 1, wherein the reactive component comprises a nitrogen-containing ring. 15. The method of claim 1, wherein the reactive component is an isocyanurate. 16. The method of claim 1, wherein the reactive component is tris(2-hydroxy ethyl)isocyanurate triacrylate. 17. The method of claim 1, wherein the reactive component comprises 5 to 50 percent by weight of the build material. 18. The method of claim 1, wherein the reactive component comprises 5 to 15 percent by weight of the build material. 19. The method of claim 1, wherein the reactive component exhibits a melting point range of 1° C. to 10° C., centered between 40° C. and 100° C. 20. The method of claim 1, wherein the at least one diluent contains one or more (meth)acrylate moieties.
