Desarrollo de un sistema extrusor para la fabricación de filamento reciclado a partir de residuos plásticos aplicado a emprendimientos

Abstract

To manufacture recycled filament from PLA plastic waste, an extruder system is designed for small businesses that use 3D printing. The design incorporates control, electronic, and mechanical subsystems, taking into account winding, cooling, temperature, and extrusion parameters. The methodology used included CAD modeling, implementation of the Marlin firmware, and experimental validation through extrusion tests. The results show that it is possible to reduce operating costs, utilize discarded material, and contribute to sustainability through polymer reuse, confirming its technical and economic viability in small-scale additive manufacturing environments.
