Abstract :

The Increasing Use Of Polyethylene Terephthalate (PET) Products Has Resulted In Significant Quantities Of Plastic Waste, Creating Environmental And Resource-management Challenges. Additive Manufacturing Provides An Opportunity To Convert Suitable Plastic Waste Into Useful Engineering Materials Through Recycling And Filament Production. This Study Presents A Sustainable Approach For Fabricating 3D-printing Filament From Recycled PET Waste. The Proposed Process Consists Of Collection, Sorting, Cleaning, Shredding, Drying, Extrusion, Cooling, Diameter Control, And Spool Winding. Recycled PET Flakes Are Processed Through A Single-screw Extrusion System To Produce Filament Suitable For Fused-filament Fabrication. The Influence Of Processing Conditions On Filament Diameter, Surface Quality, Tensile Strength, Flexibility, And Printability Is Investigated. Representative Results Indicate That The Developed Filament Achieves An Average Diameter Of Approximately 1.75 Mm With A Diameter Variation Of ±0.05 Mm. The Representative Tensile Strength Of The Recycled PET Filament Is Approximately 48 MPa, While Printed Specimens Achieve Approximately 43 MPa. The Recycled Filament Successfully Produces Test Components With Acceptable Dimensional Accuracy And Surface Quality Under The Selected Printing Conditions. The Study Demonstrates That PET Waste Can Be Converted Into A Useful 3D-printing Feedstock, Reducing Plastic Waste And The Demand For Virgin Polymer Material.
