| Abstract Scope |
Electromagnetic interference (EMI) can disrupt electronic functionality, making EMI shielding essential in device packaging. Furthermore, lightweight solutions enable protection in weight-sensitive applications. Although material extrusion (MEX) additive manufacturing (AM) offers a limited range of EMI-shielding materials, it enables geometric complexity to produce low-cost, fast-turnaround solutions that boost EMI shielding through customizable designs. This study builds on prior EMI shielding research and fabricates shields using MEX AM lattices. It uses short-fiber carbon fiber reinforced polymers and examines how lattice design variables affect EMI attenuation. Compared to other studies, this work examines a lower frequency range (30 MHz-1.5 GHz) and isolates geometric effects by maintaining constant sample mass. Results indicate that increasing sample thickness increases EMI shielding effectiveness (SE). However, a tight overall range of SE values across samples indicates a small effect from geometric differences on SE. Additionally, surface area was found to be a poor predictor of SE. |
