Different shapes and their resistivities for materials printed with the FDM method: (a) FDM printing process; (b) different materials shapes: filament, fibre, and cube; (c) resistivities of materials printed in different build orientations and frequencies of 1 Hz–1 MHz; (d) different structures of samples: solid, vertical direction and horizontal direction and (e) resistivities of the printed structure models in the vertical direction.
