Product Description

3D print circuits and RF Components with Electrifi filament. With a resitivity of 0.006 Ω cm, Electrifi is the only 3D printing filament on the market that can truly be called conductive.  The filament extrudes at a temperatures between 130-160 ºC, with a recommended printing speed of 10-45 mm/s. Electrifi is available with a diameter of 1.75 mm and 2.85 mm.  For the 1.75 mm filament, 100 g of filament  is 17 meters long.  For the 2.85 mm filament, 100 g of filament is 6.6 m long.

When you press a multimeter probe directly onto the Electrifi filament or printed traces, you’ll typically get a high resistance reading because Electrifi a flexible, which results in high contact resistance between the filament and the probe. To improve the electrical contact, we recommend using conductive pastes or screw terminals, as described in our FAQ page. The silver paste we prefer is from Electron Microscopy Sciences (product number 12640). Once the silver paste is applied, it may take around 30 min for the silver paste to dry. Screw terminals are the second best option which forms a robust connection between Electrifi and other components. Please visit the FAQ page for more details and answers to other common questions.

The filament can be used to produce many different types of circuits, including LED signs, LED matrix display, Bluetooth lamps, interfacing different types sensors with Arduino, electronic games, gaming controllers, and digital music devices to name just a few examples. If the circuit can be run with resistor of 10 ohm or greater, it can likely be made with Electrifi. Electrifi can also be used to make EMI/RF shielding, RF antennas, RF Filters, and other custom RF components.

Electrifi is shipped in a vacuum-sealed package with a desiccant packet. The filament should be stored in a cool, dry environment, and exposure to moisture should be minimized.
