Temperature flow inside the extruder is one of the most concerning parameters in 3D printing. The proper melting and extrusion of melt depend on the temperature distribution throughout the extruder. To maintain the temperature of the barrel at optimum value before the heat block, fins were attached to the barrel which ultimately acts as a heat sink to dissipate the heat into the environment from the extruder barrel and maintain it at an optimum level. To analyze the effect of different shapes of fins four different shapes (i.e. circular, rectangular, triangular, and oval) were considered during the work. In each shape of the fin temperature distribution throughout the extruder was evaluated through CFD analysis. Through CFD analysis it is found that the heat sink with an oval shape fin shows the optimum temperature range for 3D printing.
