Abstract

The development of new hybrid filaments with improved mechanical and thermal properties has been driven by the increasing need for high-performance materials in additive manufacturing. This study explores the parametric investigations of the Melt Flow Index (MFI) for Nylon6-Mica composite-based hybrid Fused Deposition Modeling (FDM) filament. The investigation uses the Taguchi technique to examine how different extrusion temperatures, loads and the percentage of Mica filler affect the MFI, a critical factor that affects how easily materials flow throughout the FDM process Results indicate that extrusion load contributes the most (69%) to MFI, followed by filler content (29%) and extrusion temperature (2%). The optimal parameters—250°C extrusion temperature, 5 kg load, and 20% Mica—resulted in an MFI of 2.411 g/10 min, comparable to commercial ABS. These experimental results highlights the crucial roles that both the extrusion load and the fraction of Mica play in optimising material performance for additive manufacturing, as they both considerably affect the MFI. The goal of this research is helps to produce efficient and affordable feedstock materials for FDM applications by establishing a relationship between these parameters and the flow properties of the Nylon6-Mica composite. The results provide insightful information that may improve material formulas and processing methods, raising the calibre and dependability of components printed using FDM technology This study establishes the foundation for future research on composite materials in FDM, encouraging advancements in the field of additive manufacturing by utilising hybrid materials that take use of both flow characteristics and mechanical capabilities.
