摘要

Recently, much work has been reported on virgin/recycled high-density polyethylene (HDPE) for 3D printing applications using the material extrusion process (MEP). However, little has been reported on the reinforcement of stubble waste powder (SWP) into the HDPE matrix to fabricate tiles using MEP. In this study, the HDPE matrix was reinforced with SWP (15% by wt.) to fabricate filament, which was used to manufacture the compressive specimen (per the ASTM-D695) as the functional prototype of the tiles. The result of this study suggests that the best parameters of the MEP based on the compressive peak strength (24.70 MPa) are infill percentage (IP) of 100%, nozzle temperature (NT) of 210 °C, and infill type (IT) triangle, and for modulus of elasticity (MOE) (143.13 MPa), IP of 80%, NT of 210 °C, and IT zigzag. The percentage improvement of compressive peak strength and MOE of recycled HDPE (without reinforcement) and HDPE reinforced with SWP was 32.43% and 61.54%, respectively. The results are supported by the photomicrographs, surface roughness (Ra) profiles, 3D render images, Fourier transform infrared spectroscopy (FTIR), and dynamic mechanical analysis (DMA).
