Auxetic structures showcase notable properties such as high indentation resistance, shear stiffness, fracture toughness, and acoustic energy absorption. Recent advancements in additive manufacturing have facilitated the creation of complex auxetic designs, but there has been less emphasis on developing new materials. This study focuses using recycled iron powders mixed with biodegradable polymers by solution casting method to create sustainable, 3D-printable materials for absorption applications. research involved examining a 2D re-entrant structure, evaluating effects varying powder concentrations polymer. The analyses included thermogravimetric analyses, differential scanning calorimetry, microstructural examination, alongside compression tests assess strength capabilities. most effective 3D-printed composite, containing 10% powders, demonstrated substantial improvement specific (SEA 2.051 kJ/kg compared neat PLA an SEA 0.160 kJ/kg) exhibited favorable mechanical thermal properties. TGA showed that adding reduced PLA’s onset degradation temperature from 340 °C 310 °C, 295 270 5%, 10%, 15% iron, respectively, confirming iron’s catalytic effect degradation. DSC analysis increased degree crystallinity 5.63% pure 5.77%, 6.79%, 6.91% indicating role nucleation agent. These results highlight potential novel iron/PLA composites energy-absorbent applications, emphasizing sustainability cost-effectiveness.
