The need for new and environmentally friendly 3D printer filament options is rising continuously. Reusing and recycling post-consumer plastic products is a promising path that can help save energy and the environment. The best appropriate material for fused deposition is determined by comparing virgin and reprocessed versions of Polypropylene (PP), High-density Polyethylene (HDPE), and Low-density Polyethylene (LDPE). Tensile strength, tensile modulus, and strain at break are among the mechanical characteristics that are assessed in comparison to standard 3D filament parameters. The results show that virgin and recycled HDPE and PP grades have good engineering qualities and are economically feasible, indicating that they can be used as substitute materials for 3D printing. These findings highlight the potential of recovered plastics to support environmentally friendly additive manufacturing procedures while solving plastic waste-related issues.
