The purpose of this work is the development of a novel hot melt ink print system, which provides a fast and customerfocused fabrication process for protective layers and sacrificial molds. The used hot melt ink is impermeable to water or other liquids and opaque against light, it can act out as a protective layer against subtractive surface structuring processes or thin and thick film deposition processes. Owing to the forming properties of the used hot melt ink the printing of 3-dimensional objects with an aspect ratio up to 115 was realized. The objects were used as sacrificial molds in combination...
