Filament Fabrication for 3D Printing Using Waste PET Material

Disposal of plastics has lately developed into a critical concern in environmental protection and trash management. Polymer composites have found application in many parts of everyday life and many industries. Along with their expanded usage, the issue of plastic waste developed since the following withdrawal from use, they became tenacious and poisonous wastes. The potential of reusing polymeric materials affords a possibility of recycling them and permits efficient waste utilization to get the goods required. The market for 3D printing is growing quickly. A broad variety of thermoplastic materials, including recyclable materials, may be used to make printable filaments for 3D printers. The goal of this project is to create 1.75 mm-diameter PET filament for 3D printing using scrap PET material and inexpensive, readily accessible components. The filament manufacturing method and machine operation are described in this paper.
