| Summary: | Extrusion methods is one of the most commonly used in Fused Deposition Modeling (FDM), and remains one of the most versatile. This study focus on the feed rate effects on filament extrusion by experimental process that was conducted. For the first step, testing jig was built to ease the extrusion process is carried out. Testing jig was designed using the FDM extruder which have made a major component in this study. From the results of the filament extrusion was conducted, feed rate plays an important role for the smooth in extrusion process. The results obtained, the feed rate applied to drive the filament into the extruder head should be between 5 mm/s until 15 mm/s only. In addition, the temperature also plays an important role in ensuring that the extruded filament can exits with ease and smooth, while the size of the nozzle also affects the filament diameter based on the material used. From the entire results obtained, the validation has been carried to all the filaments being studied by determining the suitable temperature and feed rate speed for extrusion processes especially for use in Freeform Fabrication machine. |
