| Abstract Scope |
Electromagnetic interference (EMI) can disrupt electronics 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 shield research and fabricates shields using MEX AM lattices. It uses short carbon fiber reinforced polymers and examines how lattice design variables affect EMI attenuation. Compared to other studies, this work examines a lower frequency range (0.3-1.5 GHz), used by communication, navigation, and various satellite and radio systems. Preliminary results show increased SE with decreased pore size and minimal effect from the addition of a conductive layer. The findings of this study will inform design guidelines for EMI shields tailored for specific frequency ranges and geometric requirements. |
