Redesign of an automated machine, cast plastic extruder, using PET bottles for the manufacture of filaments for 3D printers

Abstract

This work is focused on the manufacture of filament for 3D printers based on PET bottles. Going through a crushing process to generate flake, then it will be melted by depositing it in the extruder obtaining a casting process to then push the molten plastic into the nozzles with a previously established diameter, at the end of the stage will go through cooling fans allowing a better hardening of the product at the time of winding the same; thus achieving to unite in a single machine the entire process of production of filament for 3D printers. In this way we intend to join the market of the 3D printer industry and thus generating a more positive approach to society as well as improving our ecological environment.
