In contemporary industrial processes, reducing waste and promoting sustainable manufacturing practices is a crucial matter. In advanced manufacturing techniques such as additive manufacturing, the reusability and recyclability of raw materials play a critical role in enhancing production efficiency. The recycling and reusability of Acrylonitrile Butadiene Styrene (ABS) thermoplastic material, particularly in 3D printing, represent significant steps forward in waste management and material cycles within the additive manufacturing industry. Therefore, this study examines the recyclability and reusability of ABS thermoplastic material widely used in industrial production processes, focusing on its utilization in 3D printing. Initially, unused ABS filaments were granulated using a blade mill. Subsequently, these granules were extruded into filaments with an average diameter of 1.75 mm using a single-screw extrusion method. The produced filaments were utilized to manufacture tensile specimens compliant with ASTM D638 standards via 3D printing, which were then subjected to mechanical testing. In the subsequent stage, the tested specimens were re-granulated after testing. These granules were then used to produce new filaments, and the production process was repeated four times. Based on the results of the conducted tests, the impact of recycling processes on mechanical properties was investigated, and efforts were made to improve these properties. This study demonstrates the effectiveness and applicability of recycling processes in enhancing sustainability and reducing waste in industrial production. The findings contribute valuable insights into enhancing the mechanical properties associated with the reprocessing of ABS thermoplastic material and optimizing recycling processes.

摘要

In contemporary industrial processes, reducing waste and promoting sustainable manufacturing practices is a crucial matter. In advanced manufacturing techniques such as additive manufacturing, the reusability and recyclability of raw materials play a critical role in enhancing production efficiency. The recycling and reusability of Acrylonitrile Butadiene Styrene (ABS) thermoplastic material, particularly in 3D printing, represent significant steps forward in waste management and material cycles within the additive manufacturing industry. Therefore, this study examines the recyclability and reusability of ABS thermoplastic material widely used in industrial production processes, focusing on its utilization in 3D printing. Initially, unused ABS filaments were granulated using a blade mill. Subsequently, these granules were extruded into filaments with an average diameter of 1.75 mm using a single-screw extrusion method. The produced filaments were utilized to manufacture tensile specimens compliant with ASTM D638 standards via 3D printing, which were then subjected to mechanical testing. In the subsequent stage, the tested specimens were re-granulated after testing. These granules were then used to produce new filaments, and the production process was repeated four times. Based on the results of the conducted tests, the impact of recycling processes on mechanical properties was investigated, and efforts were made to improve these properties. This study demonstrates the effectiveness and applicability of recycling processes in enhancing sustainability and reducing waste in industrial production. The findings contribute valuable insights into enhancing the mechanical properties associated with the reprocessing of ABS thermoplastic material and optimizing recycling processes.
