| Abstract Scope |
The continuous increase of polymers in additive manufacturing technology harms the environment and disturbs the ecosystem. This project investigates the extrusion of recycled PET into 3D printing filament. It was expected that if the rPET pellets were compounded with some additives, such as a thermal stabilizer, a chain extender, and an impact modifier, the mechanical properties of the extruded filament would be improved. A twin-screw extruder was used to compound and extrude rPET pellets with the additives into a filament of 1.75 mm in diameter. The standard test specimens were 3D printed and tested according to the ASTM tensile, impact, and flexural test standards. The test results show that the mechanical properties of the compounded rPET are improved compared to the plain recycled PET. This conclusion suggests that the reuse of the waste polymers in 3D Printing technology will make this technology a green manufacturing technology. |
