Electrifi by Multi3D is the most advanced conductive filament on the market for FFF/FDM 3D printing: a copper-based thermoplastic compound engineered for applications that require true functional electrical conductivity, far beyond what conventional carbon-based conductive filaments can offer. With conductivity levels of up to 100,000 S/m, Electrifi bridges the gap between conductive plastics and metals, enabling the production of 3D printed parts that do not just "appear" conductive, but are genuinely conductive. This is not a cosmetic or decorative filament: it is an engineering-grade solution focused on real functional electrical performance.

What is Electrifi Conductive Filament and Why is it Different?

The vast majority of conductive filaments for 3D printers available on the market use carbon black, carbon nanotubes (CNTs) or graphene as conductive fillers. These materials are suitable for electrostatic discharge (ESD) applications, touch sensors or very low-current circuits, but they have severe limitations when true functional electrical conductivity is required. The difference becomes dramatic when comparing conductivity values and application ranges:

Material Class Typical Conductivity Typical Use
Carbon-based conductive plastics 1–1,000 S/m Sensors, ESD dissipation
Electrifi (copper-based) 1,000–100,000 S/m True functional conductivity
Metals (traditional) >10⁶ S/m Structural conductors

Electrifi uses a conductive copper particle network, providing a volume conductivity ranging from 1,000 to 100,000 S/m and a volume resistivity between 0.001 and 0.1 Ω·cm. These values make it the most powerful conductive filament for FDM 3D printing available in 1.75 mm diameter. In this version, the typical conductivity is approximately ~10,000 S/m, a configuration optimized for the most common professional applications.

Unlike carbon-based filaments, Electrifi enables the production of printed heaters, functional conductive traces, grounding structures and advanced electronic prototypes without requiring post-processing or additional wiring. The result is a fully integrated additive manufacturing workflow for functional 3D printed electronics.

Electrifi conductive filament is ideal for printing EMI/RFI shielding enclosures, enabling the creation of lightweight conductive components for wearable applications.

Electrical Properties of Electrifi Conductive Filament

Below are the key electrical properties of Electrifi conductive filament, which determine its performance in printed electronics and functional devices. These values make it possible to evaluate its conductivity capabilities and efficiency within 3D printed structures.

Property Typical Value
Volume conductivity 1,000 – 100,000 S/m
Volume resistivity 0.001 – 0.1 Ω·cm
Conductive mechanism Copper particle network
Conductivity (distribution variant) ~10,000 S/m

The actual electrical performance of Electrifi conductive filament depends on printing parameters, trace geometry and print orientation. 100% infill, wider traces and slower print speeds significantly improve the final conductivity of the printed part.

Video 2: Measuring the electrical resistance of 3D printed parts made with Electrifi conductive filament. The video demonstrates how silver paste improves measurement accuracy by reducing contact resistance, resulting in stable and repeatable readings. Based on the measurements, an approximate resistivity of 0.006 Ω·cm (~17,000 S/m) is calculated, highlighting its value for printed electronics and functional prototyping. Source: MULTI3D

Electrifi is a flexible, highly conductive copper–polymer composite filament. It is designed to maximize print reliability and electrical performance, not speed. It works best as a conductive structural material, not as a solder replacement.

1. Printer and hardware setup (CRITICAL)

  • Recommended extruder: Direct-drive (strongly recommended)
  • Not recommended extruder: Bowden
  • Not compatible: AMS or multi-material systems
  • Filament path: short, straight, and with minimal friction
  • Avoid: tight curves, long tubes, or high resistance
  • Nozzle: brass or hardened steel
  • Minimum diameter: 0.4 mm
  • Preferred: 0.6 mm or larger

2. Temperatures

ParameterRecommendation
Nozzle temperature140–180 °C
Bed temperature≤ 50 °C
ChamberAmbient (enclosure not required)

Avoid long dwell times at temperature in the hotend to reduce heat creep. Lower standby temperature in G-code if possible.

3. Speed and motion

ParameterRecommended value
Print speed10–30 mm/s
First layer5–15 mm/s
TravelModerate
AccelerationLow to moderate

Low speeds help prevent material buckling, dimensional inconsistencies, and electrical variations.

4. Retraction and extrusion control

ParameterRecommendation
RetractionMinimize or disable
Distance≤ 0.5 mm if necessary
SpeedSlow
Coasting / wipeUse with caution

Excessive retraction can cause clogs due to the filament’s soft nature.

5. Layers and geometry

ParameterRecommendation
Layer height0.2–0.3 mm
Line width≥ nozzle diameter (+10–20%)
Perimeters≥ 2
Infill100% in conductive areas

Electrical performance improves with a larger conductive cross-section, fewer layer interfaces, and shorter paths.

6. Cooling

  • Part cooling fan: 0–40% (low to moderate)
  • Avoid aggressive cooling during extrusion
  • Hotend cooling: strong and constant (critical)

7. Material handling

  • Soft and flexible filament
  • Avoid high tension or high-friction spool holders
  • Smooth, unrestricted feeding
  • Drying is usually not required
  • Keep clean and dry

8. Recommended applications

  • Printed conductive traces
  • Embedded conductors
  • Contacts and sockets
  • Antennas
  • EMI structures
  • Heating elements

Not recommended applications:

  • High-speed printing
  • Automatic material change systems
  • Long Bowden extrusion paths

9. Final practical note

Electrifi should be considered a conductive structural material. Its electrical performance depends primarily on geometry, contact pressure, and interfaces, not solely on the material’s conductivity.
