I mean it is slightly stiffer than normal pla, but as the carbon fibre is just randomnly jumbled up it doesn't really add any strength.
And while it will conduct electricity, it doesn't really do it well enough to make anything but a very weak circuit.

I've been looking for a good printable conducting filament for about 6 years. So far, nothing works well enough to be of practical usage.
Or it has so much metal in it that it's structurally too weak to be of any use lol

I even went down the electroplating route. And the 'conductive' cf filaments don't even conduct enough electricity to electroplate them.

You can use abs and paint it with a 'paint' made from graphite powder and acetone - that works quite well but between the acetone and the abs print-stink, It's just not something I like doing.
