| dc.description.abstract | The increasing use of 3D printers has heightened the need for sustainable solutions to manage the polymeric waste generated, such as PLA. This study presents the development of an innovative shredder capable of processing 3D printing waste and transforming it into reusable granules for the production process. The project involved the design of a knife mill, adapted for PLA, with blades offset by 30°, ensuring efficient distribution of cutting forces and reducing stress on the components. Critical components, such as blades, shafts, and motor, were dimensioned using precise calculations to determine cutting force, torque, and material resistance. The system was validated through finite element analysis (FEA), ensuring structural robustness and an adequate safety factor. The system allows for the adjustment of granule size using sieves with different calibers, making it adaptable to process requirements. It also includes safety devices that ensure reliable operation and protect the operators. The equipment proved versatile and capable of processing common polymers such as ABS, PETG, and PA. The results confirm that the shredder is a practical, efficient, and sustainable solution, contributing to the circular economy and reducing the environmental impact of 3D printing. In the future, improvements in design and automation could enhance its scalability and facilitate integration into industrial processes. | eng |
