Abstract: In one aspect, build materials operable for use in 3D printing systems are described herein. In some embodiments, a build material comprises about 10 to 30 percent by weight of an oligomeric curable material; about 50 to 75 percent by weight of at least one diluent; and about 3 to 15 percent by weight of a reactive component. Moreover, in some cases, the build material is free or substantially free of a non-reactive wax component.

Abstract: There is provided compositions and methods for producing three-dimensional objects by selective deposition modeling with a polar build material and a non-polar support material. The build material comprises a hydrocarbon wax material and a viscosity modifier, and the support material comprises a hydrocarbon alcohol wax material and a viscosity modifier. After the selective deposition modeling process has been completed, the object can be placed in a bath of polar solvent to remove the support material. The particular materials provided herein, and the post-processing methods associated therewith, provide for improved part quality of the three-dimensional object and for improved post-processing techniques. The three-dimensional objects can subsequently be used in a number of applications, such as patterns for investment casting.
