Conductive 3D Printing Filament - Resistance/Power Test

In this video I will have a look at the currently most promising conductive 3D printing filament in order to find out how easy it is to print with, how high its resistance is and how much power it can handle.

Just crank the heat of your printer up and directly put your copper wire in

hi, metal filled matrices need curing, about 150-200
Celsius. I think the conductivity would increase if you print it out. if you can't just put in the oven for half an hour.

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've used graphene as the conductive material in a project this year, though we had some problems with surface resistance being too high. To be able to connect LEDs etc. to a given circuit, we had to paint the connection point on the 3D printed part with a silver ink pen (found somewhere on Amazon). Once the paint had been applied, the circuit would work flawless. We even had some students do a masters thesis on this, where they came up with some different 3D models to build different circuits etc.
Another problem we experienced with graphene was that it requires a larger nozzle than a standard 0.4 mm as it would clog up pretty fast.

I was thinking that this could be used when 3D printing cases for hardware. If you somehow tell the slicer to use different printing head for only inner walls, you can make a shielding from this material.

This could be somewhat useful if your printer supports using two or more types of filament simultaneously, if you want to make something extremely complex. I think I would still prefer to have a few spools of copper wire of different thicknesses. Maybe even some aluminium wire.

For 100g is $200 dollars! It's expensive D:

I noticed the tests you conducted mainly consisted of using the raw filament or the giant thick cylinder. In real world if this was used on a circuit board, you would be using a much thinner layer of material. I wonder if the thickness of the print affects the resistance and heat/melting point. This could explain the contact area hotspots as they were giant blobs.

Thank you for all your videos! I always learn something new!

[gurjeetsaini]

he never forget to say "with bolts and nuts" :)

[clarencecherrone]

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.

[johndoe]

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.

Hey scott please add wishlist my wish's :D

1. DIY (Cheap) Camera Gimball
2. DIY Electric Cycle
3.Solar Panel Boost Conventer

Thx :D

[DoonRiderMaharsh]

sir u r the greatest source of my inspiration i had interest in electronics but after seeing ur videos i have started understanding them much better i pray to god that u live a long and healthy life and continue to teach us great things thankyou sir for giving us so much knowledge and i m your biggest fan😊

[GRADIENTES]

Thanks man! I'm trying to learn more about this filament. I have used it in an Ultimaker, but I usually have a lot of problems with the nozzle.

[larseastman]

I wish i could have a nice hand writing like you do!

[whollymindless]

It's good to learn the limits of the material. There are lots of dream projects in these comments that. would be crushed if they understood the video. Thanks for sharing the reality of conductive filament.

[bkvdpw]

I enjoy your videos - clear, well researched, and understandable - particularly for an an easily-confused sexagenarian. But, I have to say, I really like your handwriting!!

[Patrik]

Conductive filament? I always learn new things here :D

[NicholasAarons]

That Was Fantastic Dude. Very Cool. Keep up the great work. Nick.
