conductive filaments

[aag 5]

I am considering using conductive filaments for low-voltage applications (sensors etc.). I was wondering whether anybody has done that, and whether you could share your experiences (quality of various filaments) and tips. Many thanks in advance.

No experience myself.

 

But when looking at pictures of dual-nozzle, dual-material prints, we often see tiny strands of material 1 embedded in material 2. The same hairs and string that we see on single nozzle printers, and that we wipe off or cut off. But then unremovably embedded into the other material. So I think there is a high risk of short circuits. In addition, it would be suitable for high-impedance applications only, like anti-static. It would require quite a lot of testing and fine-tuning, I think. Unless you would print the conductors and insulators separately, clean them up, and glue them together. I could see that working in let's say model railroad trains and houses. Or in low-voltage touch sensors, or so.

 

If I remember well, this has been discussed a couple of years ago? Maybe you can find that post again? It might be outdated, but maybe there are still good tips in it?
