Abstract
A method for solid free form fabrication includes providing a dispensing head, printing one or more support material layer(s) with the dispensing head and forming vacancies within the one or more support material layer(s), and filling the vacancies within the one or more support material layer(s) with a modeling material. The method also includes straightening the modeling material with a leveler to form a three-dimensional shaped object and removing at least a portion of the one or more support material layer(s) from the three-dimensional shaped object.
