This has one fantastic application which I can think of: 3D printed fixturing for ESD sensitive devices.
You can print any sort of fixturing you need, then ground it as you would a metal fixture and bam you have a cheap and easily replaceable fixture that is safe for processing static sensitive product.

I wonder if it conducts better along the printing plane, rather than crossing the layers. The nice part about using it with LEDs is that it can be the current-limiting resistor. It could also be used to print low-temperature heating elements, like a reptile heat pad; it'd even fail-open if it overheated.

its really usefull when you want metal electro plating with copper, zink, nickel or aluminium the print for more durabillity and a better look on the other hand you can Grind PETG filler it paint it with conductive silver and electro plate it after. looks also way better and not anymore like a 3d print

Im interested to know how contact resistance would be affected by dielectric grease. I can see this being useful for replacement buttons with conductive carbon contacts and replacement battery doors that originally had a plate of metal. Then again, copper or aluminum tape often works well enough.

Contact resistance with probes is negligible.
I did see around 50 leds, times 20mA (lowest guess) for each led.
Which requires 1A at 5V = 5Watts of power, maybe a little less.
The tracks of the cuircuit were pretty thick and wide, though.

you could have measured the resistance as a function of filament length. if you plot it then the y-intercept is the contact resistance and you can obtain the desired value from the slope

Try putting a tube between the bearing and gear of your extruder. File down each side of the tube so it fits tight between them. I used a replacement hot-end tube with teflon lining.

Well, there it is. After years of trying to justify it and not seeing this video, I finally have a good enough reason to add a second nozzle to a printer.

3d printing electronics seems like very niche usage to me, but the real question is: Can this be used for direct 3d print to galvanic electroplating?
