•3D printed vent structures offer EMI shielding and thermal cooling via air circulation•Additive manufacturing combined with nanomaterials shows great potential in shielding•High aspect ratio silver nanowires make continuous conductive grid on the structures•With 2mm height honeycomb cell size, structure offers up to 35dB attenuation X-band•Intricate honeycombs attenuate EM waves primarily through absorption (up 70%) In light of rapid advancements within electronic industry, urgent need for development implementation advanced electromagnetic interference (EMI) materials has become paramount. Herein a novel approach is presented developing lightweight using 3D printing technology, subsequent spray coating, containing Silver Nanowires (AgNWs), achieve effective as well functionality cooling.Using polyol method, AgNWs were synthesized having high crystallinity be used coating structures. The results X-band demonstrated that developed exhibit promising properties, 35 dB making them suitable applications requiring protection along venting. More importantly all samples major contribution efficiency comes from 75%) inside which helpful reduce reflected noise.Effort was effectively addresses inherent limitations conventional processing by additive material science create applications, bridging gap between existing desired components. cooling.

The application of copper surface coating to plastic structures offers numerous advantages, including high thermal and electrical conductivity, improved mechanical properties, good corrosion resistance, decorative applications, enhancements in working temperatures. Besides these producing with 3D printing applying enables the final become functional adaptable different fields. In this study, were produced using fused deposition modeling method. Pristine, dichloromethane dipping, vapor, cold oxygen plasma, abrasion treatments applied determine optimal treatment between substrate before coating. Subsequently, on was completed DC sputtering technique. topography, optical, electrical, structural properties examined. According X-ray diffraction analysis results, (111), (200), (220), (311) crystal planes confirm presence copper. conductivity values reached 7.87 × 10 5 S/m. Contact angle measurement results indicate that increased contact angles 88.309°, leading coated exhibit a more hydrophobic behavior.
