Abstract : This project titled “Design and Development of a 3D Printing Filament Extruder” aims to create a cost-effective and efficient system for producing high-quality 3D printing filament using thermoplastic materials. The main objective is to design and fabricate an extruder that can convert raw plastic pellets or recycled waste into consistent filament suitable for Fused Deposition Modeling (FDM) 3D printers. The system comprises essential components such as a feed hopper, screwdriven extrusion mechanism, heating barrel, temperature control unit, nozzle die, and filament winding assembly. The design focuses on achieving precise temperature control and uniform extrusion to maintain a consistent filament diameter. The developed prototype was tested using materials such as PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) to evaluate its performance in terms of extrusion rate, filament quality, and dimensional accuracy.
