Finite Element Analysis of a FDM 3D Printer Liquefier

Abstract

This paper deals with the analyzing and comparing the thermal performance of heat dissipation system and other components in the design of E3D liquefier using Finite Element Modeling (FEM) for three different filaments namely Polycaprolactone (PCL), polylactic acid (PLA) and Acrylonitrile Butadiene Styrene(ABS). This work evaluates the influence of airflow generated by means of a fan coupled to the extruder. The printable materials are also taken as variable in this investigation. The heating process should ensure the balance between proper heating of the material and controlling the temperature along the extruding body, so it reaches above 140 degrees in function of raw material on the tip of the nozzle and must be lower at the top of the liquefier for the correct perseveration of the 3D printer and its durability.
