This study focuses on the development of a sustainable and high- performance composite filament by incorporating groundnut shell-derived carbon into ABS (Acrylonitrile Butadiene Styrene) for 3D printing applications. The aim is to utilize agricultural waste, specifically groundnut shells, to improve the mechanical and thermal properties of the polymer while contributing to sustainable manufacturing. Groundnut shells, a lignocellulosic by-product, were crushed, sieved, and integrated into ABS using melt extrusion techniques. Filament production involved optimizing filler loading percentages and ensuring consistent extrusion quality.

Comprehensive testing, including tensile,

flexural, and thermal analyses, was conducted to evaluate the performance of the composite. The results indicated significant enhancements in mechanical strength and thermal stability, showcasing the potential of groundnut shell- derived carbon as a viable natural filler. The approach not only reduces environmental impact but also offers a cost-effective alternative to conventional materials.

Applications in various industrial sectors, including automotive and consumer goods, were identified, emphasizing the utility of this innovative filament in advancing eco-friendly 3D printing. Future work will focus on refining the filler compatibility and exploring surface treatments for further performance improvement.
