Electromagnetic pollution has become a major issue in modern society; the design and development of materials for wave absorption hold significant importance domain electromagnetic shielding protection. In this research, dual-stage procedure consisting mechanical milling followed by thermal extrusion was used to prepare carbon nanotube (CNT)/polylactic acid (PLA)/thermoplastic polyurethane (TPU) composite filaments. The composites CNT/PLA/TPU were successfully fabricated through fused deposition modeling techniques. study systematically explored impact CNT analysis on properties, parameters, composites’ performance absorption. findings reveal that PLA/TPU-based demonstrate excellent characteristics, including tensile strength 24 MPa an elongation at break 19%. When content 4 wt. %, achieved Rlmin −31.21 dB effective bandwidth (EAB) 5.52 GHz 2.0 mm thickness. Compared with existing studies, research highlights potential achieve wave-absorbing properties low content. attenuation capability is significantly enhanced collaborative interaction multiple reflections, conductive loss, dipole polarization, interfacial polarization. results not only provide novel perspectives into efficient but also lay foundation area
