Abstract

This study explores the effects of feed rates on temperature profiles and feed forces in material extrusion additive manufacturing of polymers. The relations between temperature distributions and feed rates are first derived, for both the solid and melted portions of a polymer during its extrusion. The derived relations are then applied to find the temperature profile for the case of acrylonitrile butadiene styrene (ABS). Finally, an existing relation between feed force and feed rate is considered. Its applicable range is determined, validated by experimental tests on ABS.
