Abstract
A method for removing supports from a three-dimensional object formed by solid freeform fabrication. The three-dimensional object and support structure both contain a phase change component in order to achieve the desired phase change characteristics needed for dispensing the material. The method prevents the phase change material within the three-dimensional object from migrating within the object during post processing to remove the support structure.
