520			_aThe increasing demand for sustainable and cost-effective solutions in 3D printing has driven the exploration of innovative recycling methods. This study focuses on the development of a 3D printing filament extrusion machine designed to utilize polyethylene terephthalate (PET) bottles as a 3D printer filament. The machine integrates a custom- designed extrusion mechanism, temperature control, and semi automation using an Arduino Nano and a motorized stripping module to produce filament from recycled PET bottles. The project prototype has five sections namely extrusion section for which the PET is converted into filament, stripping section that turns the PET bottle into strips, controller section for controlling the system, spooling section for storage of strips and extruded PET bottles and the case section for the base which maintains all machine components while keeping them stable. Several types of PET bottles were tested to evaluate its viability as extrusion material based on factors such as extrusion time, strip length, and filament quality. Experimental results showed that Bottle 1 produce a strip bottle from trail 1 to 3 with a length range from 1.9m to 2.3m and produce a filament of 1.9m to 2.3 m. Bottle 2 shows a result of 1.24m to 1.24m in length and with no filament produce. Bottle 3 shows a result of 1.23m to 1.24m strips produced and with a filament measuring 1.23m to 1.24m. Bottle 4 has a length of strip bottle of 2.9m to 4.5m and the filament produce is between 3.9m to 4.1m. Bottle 5 produce a length of 1.23m to 1.25m and with a filament length produce of 1.23m to 1.26m ,with an optimal temperature range of 220-240°C for extrusion. The respondents evaluated the prototype as “excellent” across various criteria, yielding and overall mean of x̅=4.91. The findings of this research demonstrate the potential of transforming PET waste into valuable filament for 3D printing applications, contributing to both environmental sustainability and the advancement of low-cost 3D printing technology.
