Hybrid additive manufacture: Surface finishing methods for improving conductivity of inkjet printed tracks on non-planar substrates fabricated using fused deposition modeling

•Fused Deposition Modeling has the potential to create customized embedded sensor systems if hybridized with InkJet methods.•The as-printed surface finish of printed components results in poor conductivity or continuity breaks in the InkJet tracks.•Three surface finishing methods are investigated: nozzle ironing, subtractive machining and burnishing.•Burnishing yielded the most desirable results, increasing conductivity and reducing continuity breaks in the InkJet tracks.•Burnishing is attractive for hybridizing additive processes for “click-to-manufacture” fully embedded sensor systems.
