2. Why Electrifi™ Is Fundamentally Different from Carbon-Based Conductive Filaments

Educate users on the physics difference between carbon-filled and metal-filled composites.

ELECTRIFI 101

1/2/20261 min read

Carbon-based conductive filaments rely on sparse conductive pathways formed by carbon particles dispersed in a polymer. These pathways are fragile, highly resistive, and sensitive to processing conditions.

Electrifi™, by contrast, forms a dense, interconnected copper network inside the polymer. This metal–polymer composite behaves very differently:

  • Much lower resistivity

  • Higher current-carrying capability

  • Strong dependence on geometry and contact design

This is why Electrifi™ can support applications like heaters, antennas, and EMI grounding—tasks that carbon-based plastics struggle to perform reliably.

However, this also means Electrifi™ must be designed and printed differently than standard filaments.
