What is the ohm per cm ?
I tried some of this and was useless, resistance way too high to be used as conductor
@Shachar_Weis 1 ohm-cm.
@Peter_L Which filament did you try?
@Sally_Bowyer They filament I bought was http://www.xpstechnology.com.au/product/super-premium-1-75mm-conductive-abs-filament-starter-pack/ and they quote 10K per cm but I found when printed to is about 500K, if that is 1 ohm-cm then that would be good
One thing that makes a big difference is contact resistance. Often the bulk of a material can have reasonably low resistivity, but if the microscopic conducting particles don’t stick out of any surface formed the contact resistance can be very high.
