    摘要： 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.
