In this project, we'll use conductive filament to create a coin cell battery tester. Using a 3D Printer with dual extruders, we can combine conductive and PLA materials!
This is conductive filament prints like PLA and conductive enough to make working circuits.
Combines with other PLA materials with good layer adhesion. Made from PLA, a dispersant and conductive black carbon. It’s a bit more flexible than PLA.
How conductive is it?
It’s 30 ohm-cm per centimeter. Thats volume resistivity, which is the resistance through a 1cm x 1cm cube of material. It’s resistivity changes depending on features.
3D printed parts perpendicular to layers, through z-layers have a difference of 85 ohm-cm.
Great choice for low-voltage circuitry like capacitive touch sensors and parts that interact with touch screens.
This will easily run a low current arduino, if you’re not powering much with it.
