Analysis on Influence Factors of Extrusion Filament Process of FDM

The paper presents the process for delivering and extruding filament of FDM (Fused Deposition Modeling) and its involved pulse generator and stepping motor driver. The relationship between filament-delivering rate, screw rotating speed and extrusion flow rate has been expounded, and the measurement values of extrusion flow rate are given by experiment. Finally, the paper analyzes influencing factors of extrusion filament process emphatically, and indicates the significance of reasonable combination of the influence factors for normal extruding filament.uenceFactorsof
