Abstract
With the increasing concern for the environment and the need to recycle materials, the development of equipment that enables the production of filament for additive manufacturing from PET bottles has gained prominence. These devices transform PET bottles into filaments that can be used in 3D printers, although filament production is currently done manually, and the obtained results are not well understood. In addition to being a sustainable solution, this practice can also generate cost savings for users of 3D printers, as filament produced from PET bottles can be cheaper than pre-purchased filament. This article describes the development of equipment capable of producing filaments for additive manufacturing from PET bottles. Furthermore, the study analyzes the influence of parameters such as motor rotation speed, cut filament width, pre-heating, and heating temperatures in the equipment, and compares the strength of the final material with commercial products. The goal is to evaluate the feasibility of using PET bottles as a low-cost alternative to produce filaments for additive manufacturing, as well as to understand how equipment parameters affect the quality of the resulting filament. Solidworks software was used to create the CAD model for equipment design. Additionally, a PID control strategy was implemented for its operation using Arduino. In the evaluation process of filament produced from PET bottles and its comparison with commercial products, tensile tests were performed. The results showed that lower temperatures result in filaments with higher mechanical strength. Furthermore, the results indicate that it is possible to produce high-quality filaments from recycled plastic waste while maintaining suitable mechanical and thermal properties for additive manufacturing. These findings are important for the sustainability and environmental impact reduction in the additive manufacturing industry.
