Abstract—Additive manufacturing techniques are prominently being used presently in the day-to-day manufacturing of products. FDM process, one of the widely used additive manufacturing technique, involves the semi molten filament of plastic that is extruded from heated nozzle and deposited over print table where it gets cooled and solidified by transferring the heat to surrounding which is maintained at relatively very low temperature. Simultaneously deposited filament forms bond with adjacent filament. Heat transfer from the filament occurs in the form of conduction and convection. Therefore, the effect of convection coefficient on bond formation is studied. Also the methodology for prediction of bond dimensions with respect to convection coefficient for the given set of parameters is presented. The procedure to achieve the desired time required for the bond formation is also been attempted.
Index Terms—Additive manufacturing, fused deposition modelling, bond formation, convection heat transfer coefficient.
