EasyChair Preprint 8847

Abstract

Globally, Indonesia is the second-largest contributor of plastic waste with millions of metric tons dumped into oceans yearly. Therefore, this research describes the process of recycling HDPE waste to produce new products in the form of filament for self-supplying 3D printed material in two phases. The first is the preparation, which focuses on shredding HDPE waste, while the second implements the extrusion process at various levels. The parameters selected in this process are the time span, the temperature, and the shrew speed. The input material for the extruder machine is set for four variations of HDPE and resin ratio, namely 90:10, 92.5:2.5, 95:5, and 97.5:2.5. In the extrusion process, the parameter and level variation are studied to produce the desired filament. The mechanical properties of each filament are tested to determine their tensile and bending strengths. The tensile test result showed that the greater the ratio of HDPE and resin, the smaller the elasticity value of the filament. Conversely, the bending test result indicated a linear relationship between the elasticity value and the ratio. The slope of -43.40 MPa and 35.70 MPa for tensile strength and bending tests signifies that for every increasing one percent of composition, the elasticity filament decreased by 43.40 MPa and increased by 35.70 MPa, respectively. This study provides numerous academic benefits, such as minimizing plastic waste in the surrounding environment, becoming a topic of study for the students, and self-supplying the 3D printed material.
