Investigation on the Performance of Multi-Layer Printed Conductive Tracks on Multi-Layer Printed Insulator

The move to multi-functionality in Additive Manufacturing converges a number of technical challenges, notably the accurate and reliable deposition of different materials and their interaction. In this paper, an investigation on the pattern quality and conductivity of multi-layer printed conductive tracks on multi-layer 3D printed insulator was carried out using a drop-on-demand inkjet technique. Results have shown that the surface finish of the printed insulator had a significant effect on the performance of the conductive tracks that have been overlaid. Also the printing strategy used in the processing resulted different width, height, conductivity and pattern quality of multi-layer printed conductive tracks.
