Abstract
AbstractRecently 3D printing or additive manufacturing has been one of the most popular techniques for fabricating material. 3D printing or additive manufacturing has taken over the modern material fabrication industry in a revolutionary manner. The present review focuses on designing electromagnetic interference (EMI) shielding materials by 3D printing. The various raw materials such as polylactic acid (PLA), polypropylene, graphene, carbon nanotube (CNT), multiwalled carbon nanotube (MCNT), and so forth, can be successfully used for making effective EMI shielding performances in different frequency ranges. These raw materials have prepared diverse shapes, dimensions, and compositions to attenuate the incident radiations over the shielding material's surface and ultimately protect the electronic devices. When mixed with carbon nanotubes, PLA has been shown 8–15 dB, 30 dB, and 67 dB EMI SE in different frequency ranges, a material with ABS and CNT have −3 to −16 dB reflection loss in X‐band frequency. Also graphene nanofilm/MWCNT composition has shown EMI SE as high as 43–54 dB in X‐band ranges when printed with poly jet printing. These properties gave a cutting‐edge rivalry to the conventional fabrication method and proved that 3D printing is better when designing innovation for EMI shielding materials
