great for printing electrical circuits. Other brands I have used are extremely brittle. I am going to test this before giving any recommendations. contact resistance is quite high so a large surface area for connecting to electrical wires is needed. we suggest fanning out the end of the wires and holding it in place while printing the next layer then a few layers later flip the tips back over for another pass of the nozzle. this distributes the heat at the junction and allows a good connection. alternatively, heat up a metal pin and insert deep into a patch of the conductive filament.
