Abstract Electromagnetic interference (EMI) significantly affects the performance and reliability of electronic devices. Although current metallic shielding materials are effective, they have drawbacks such as high density, limited flexibility, poor corrosion resistance that limit their wider application in modern electronics. This study investigates EMI properties 3D‐printed conductive structures made from polylactic acid (PLA) infused with 0D carbon black (CB) 1D nanotube (CNT) fillers. demonstrates CNT/PLA composites exhibit superior effectiveness (SE), achieving 43 dB at 10 GHz, compared to 22 for CB/PLA structures. Further, coating polyaniline (PANI) electrodeposition onto improves SE 54.5 GHz. strategy allows fine control PANI loading relevant tuning SE. Additionally, PLA‐based offer several advantages, including lightweight construction enhanced resistance, positioning them a sustainable alternative traditional metal‐based materials.

3D printing has emerged as an attractive manufacturing technique in supercapacitor electrodes owing to the precise and customisable fabrication of complex electrode designs, enhancing performance efficiency device. Despite advantages, 3D-printed are limited by their low conductivity electrochemical properties, predominantly due lack availability suitable conductive materials. To address this limitation, we modified nanocarbon (3D-PnC) activation surface deposition Ti3C2Tx MXene. A solid-state asymmetric was fabricated using 3D-PnC/Ti3C2Tx negative polyaniline (PANI) electrodeposited (3D-PnC@PANI) positive electrode. The symmetric exhibits enhancement overall voltage window, areal capacitance energy density. successful operation demonstrated illumination red light-emitting diodes. Furthermore, research opens possibility utilising MXene-modified for various applications devices.
