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. These findings indicate can be substantially improved through low‐cost straightforward electrodeposition, enabling production customized performance. novel fabrication method offers promising potential developing advanced solutions

Fused Filament Fabrication (FFF) is one of the most emerging techniques nowadays. Affordable, easy to use, economical, for a broad audience − from specialists home users. These are only several its advantages. A disadvantage limited number available filament types, especially those with high performance. Therefore, aim work was investigate properties custom–made printouts based on polylactic (PLA), graphite (G) and molybdenum disulfide (MoS2). This looked at structural thermal analysis, acoustic performance, EMI shielding, electrical properties, including conductivity heat diffusivity. The following were considered during study: type printing architecture, infill density, formulations. Among best values, which obtained highest loaded sample 15 wt% 2 MoS2 (G15/M2), where shielding effectiveness surpassed SETOT ∼ 17 dB (per 1 mm thickness), remained low level. It exceeded σ 0.2 S/m; slightly over κ 0.4 W/mK, diffusivity almost α mm2/s. first step in designing high-performance materials dedicated advanced applications FFF technique.
