Electromagnetic characteristics of filaments for 3D printing with carbon fillers in the microwave range

The results of a study of the complex permittivity and electromagnetic response from polymer composite materials obtained by additive technology from 3D printing filaments containing various carbon fillers are presented. New radio filaments for 3D printing with MWCNTs have been created. Investigated PLA-Conductive plastics may be used to create a shielding coating or narrowband absorbers for microwave range
