Abstract

There is provided compositions and methods for producing three-dimensional objects by selective deposition modeling with a polar build material (30) and a non-polar support material (31). The build material (30) comprises a hydrocarbon wax material and a viscosity modifier, and the support material (31) comprises a hydrocarbon alcohol wax material and a viscosity modifier. After the selective deposition modeling process has been completed, the object (44) 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 (44) and for improved post-processing techniques. The three-dimensional objects (44) can subsequently be used in a number of applications, such as patterns for investment casting.
