In a commercial 3D printer head, plastic ribbon passes through a hot nozzle of an extruder to dispense liquid plastic droplets to construct the model. In this paper a 2D axisymmetric model of a 3D head is considered to study the secondary transition change from below the glass temperature to above the glass-transition temperature of ABS (Acrylonitrile Butadiene Styrene) using COMSOL Multiphysics® Software. The transition from the glassy to the molten state of ABS is modeled using the heat capacity model. A narrow secondary transition is observed during the glass-transition temperature.
