A method of manufacturing an ink stick for use in a phase change ink jet imaging device comprises heating phase change ink material to an extrusion temperature at which the phase change ink material is in a malleable state. The ink is then extruded through an extrusion orifice to form at least one extruded ink filament having at least one cross-sectional dimension transverse to the extrusion direction that is less than approximately 12 mm. The at least one ink filament is then accumulated.
