Most people assume conductive filament behaves like a wire.
It doesn’t.
Current flows by hopping between particles—and that changes everything.
We summarized the fundamentals in 1 minute.

Measured your conductive filament and got an “open circuit”? 🤔
It’s usually not the material—it’s the contact.
Improve the interface (e.g., silver paste) → see the true conductivity ⚡

Not all conductive filaments are equal ⚡
Carbon-based filaments are great for static dissipation, while metal-based filaments enable true electrical functionality.
Same form factor—completely different performance.
Not all conductive filaments are the same ⚡
Carbon ≈ 100 S/m
Metal ≈ 100,000 S/m
Material + particle contacts = huge performance gap

3D printed EMI shielding enclosure ⚡
Made with carbon-based conductive filament.
Looking to test shielding performance—
anyone have EMI/EMC capability?
This is NOT a metal wire ⚡❌
Conductive filament works differently—electricity hops from particle to particle.
Most resistance comes from the contacts between particles.
Better contacts = better conductivity.

Most plastics don’t conduct electricity ⚡❌
But add enough conductive particles… and suddenly everything connects.
That moment is called percolation — where a small change leads to a big jump in conductivity.

Can you 3D print something that carries electricity? ⚡
Most plastics can’t—they block electricity.
But conductive filament changes that.
It works by creating tiny pathways inside the material that allow current to flow.
