The extruder is designed for producing filament that can be used for 3-D printers. The 3-D printer requires a filament having dimension ranging from 2-2.5mm. The quality expected is to obtain continues filament having the specified dimensional range which can be fed in to the 3D printer. Screw extrusion process is adopted to produce filament to fixes cross section. PET pellets were heated between 230° to 250° and pushed through a nozzle. The material experiences compressive and shear force. A continues filament of diameter ranging from 2 to 2.5mm is obtained without any air bubbles and roughness.
