Fabrication and analysis of ABS-HDPE-PC composite polymer filament used for FDM printing using hybrid algorithm.

The proposed work presents a novel composite polymer filament made by blending High-Density Polyethylene (HDPE) and Polycarbonate (PC) with Acrylonitrile Butadiene Styrene (ABS), resulting in improved properties such as strength-to-weight ratio and impact resistance, expanding the applicability of ABS in healthcare, automotive, and engineering industries. The composite polymer filament was fabricated using a single screw extruder at different parameters like barrel temperature, rotational speed of the screw and different thermoplastic polymer compositions. The tensile strength was measured using a Universal Testing Machine (UTM). The input/output data were optimized using hybrid tools, including genetic algorithm artificial neural networks (GA-ANN) and response surface methodology (GA-RSM). The results obtained from GA-ANN were validated experimentally, demonstrating a maximum tensile strength of 39.8 MPa at 280 °C, 10.001 RPM, 16.783%wt of HDPE, and 8.839%wt of PC. It is observed that the proposed work with GA-ANN model effectively improved the tensile strength by 7.2% in comparison with GA-RSM. This research highlights the potential of the proposed composite material in various applications, emphasizing its cost-effectiveness and improved mechanical properties. [ABSTRACT FROM AUTHOR]
