Design and Development of an Extruder Machine for Converting Recycled PET Plastics into 3D Printing Filaments

Abstract

This paper presents the design, development, and implementation of an extruder machine for converting recycled polyethylene terephthalate (PET) plastic into 3D printing filament. The primary objective of this project is to provide the Universidad Tecnológica de Bolívar (UTB) community with an innovative tool that promotes plastic waste reuse, contributing to environmental impact reduction and fostering the development of sustainable community projects. The extruder machine is designed as a laboratory tool to facilitate the production of recycled PET filament, supporting research and practical applications in additive manufacturing.
