WebApr 11, 2024 · As shown in the graph, the resistivity of the planarly 3D printed samples increases with the angle of incline. Higher degree of incline means more print layers, which in turn means that the resistivity of the planarly printed traces relies more on inter-layer bonding than intra-layer bonding, which results in poorer conductivity of the traces [36] .
