The linear “take–make–dispose” model of plastic consumption has led to significant environmental challenges and unplanned waste legacies, emphasising the need for more sustainable recycling practices. This study explored integration post-consumer recycled polylactic acid (rPLA) into 3D printing filaments as a step towards manufacturing. Using 100% virgin PLA (vPLA) baseline, were produced with rPLA-to-vPLA ratios 0%, 25%, 50%, 75%, evaluated surface roughness, tensile strength, flexural properties, hardness. results revealed that increasing rPLA content negatively affects mechanical properties quality. Surface roughness increased from 7.06 µm pure vPLA 10.50 rPLA, whilst strengths decreased by 48.4% 49%, respectively, compared vPLA. Hardness also declined, showing 7.5% reduction relative Despite these reductions, blends up 50% retained over 90% performance vPLA, demonstrating viable compromise between sustainability. Morphological analysis highlighted poor interlayer adhesion void formation primary causes degradation in higher blends. challenges, this demonstrated rPLA-vPLA can extend life cycle promote manufacturing By addressing polymer research supports materials printing, contributing circular economy goals recycling, resource efficiency, production outcomes.
