The folks have made a magnetic levitator, for one I'd like to see a 3D printed Tesla Coil primary and possibly secondary if the filament is thin enough.

Can't let abuse of units go unchallenged. The promoters said less than 1 ohm/cm, but let's say they mean 1 ohm-cm (the proper unit for volume resistivity).
Conundrum, how did you come up with 0.1 ohm per meter for 10 strands? With the stated resistivity, a filament 1 cm x 1 cm x 1 meter would be 100 ohms the long way. (rho*L/A).
Metals generally conduct electricity millions of times better than that goo. For tesla coil windings, I recommend sticking with metal.

OK, lets assume they mean 1 Ohm cm. That's 0.01 ohm metres so you can compare it to the list here and it turns out to be roughly as good a conductor as sea water.

Im all in for printing circuits with unconventional methods, as I have the same flash forge printer they're using. but ive seen alot of people try and not get far. it seems enough plastic to thermally extrude, results in so little metals particles, that it has a high resistance for a given would-be trace.
id be willing to make parts for those here on the forum with conventional PLA, Nylon and ABS, but we should get the electrical characteristics first. for a minor profit of course.
