ABSTRACT

Filament extruder produces plastic filaments with specified diameter by using corresponding nozzles. Input materials are used in the form of granules and pellets and waste materials of the FDM printer can be used. Band heaters are used to melt the input materials and Screw is used to feed the input raw materials longitudinally along the barrel. Screw is consisted of three zones namely feeding, melting, and metering zone. Required raw material is melted by using band heater. Two temperature zone with two band heaters are used to acquire maximum efficiency. Analog temperature controller is used to control the temperature of the two heaters zone. This project describes a filament extruder, which is a plastic extruder capable of making commercial quality 3D printing filament. Our project includes the design, fabrication and operation of a filament extruder. A 2.0 mm nozzle is used to extrude the filament at the diameter of 1.75mm. Production can be further increased by increasing the barrel diameter and screw diameter.
