Production and characterization of biodegradable polylactic acid composites 3D filament from agro waste

Eco-friendly additive manufacturing products can be made by producing 3D filament from biodegradable materials. In order to create composite filaments, a twin-screw extruder was used in this study to combine 100 μm tamarind seed shell powder. In this study, polylactic acid (PLA) composite filaments for biomedical applications were reinforced using tamarind shell powder (TSP) as a filler material. To create the composite filaments, TSP was added to PLA at loading ratios of 5% and 10%. Examined were the manufactured composite filaments’ mechanical characteristics and microstructure. More than other filaments, the tensile strength of 10 wt% of the produced 100 μm-size filaments was superior. As demonstrated by the results, the reinforcement improves the composite filaments’ mechanical qualities. The SEM analysis demonstrated matrix and reinforcement interfacial adhesion that is exceptionally robust. These tamarind seed shell/PLA bio composites’ good qualities and inexpensive cost make them suitable for usage as biodegradable filaments in 3D printing applications.
