Conductive Filament

Conductive Filament is specifically designed to allow 3D print electrically conductive components. With the addition of conductive carbon particulates to PLA or ABS, it easy to 3D print low-voltage electronic circuits, buttons, power connectors, and Raspberry Pi cases.

PRODUCT DESCRIPTION

Practically all the conductive filaments available in the market today are composed of a mixture of carbon and a standard 3D printing plastic. Commercially available conductive filaments come in different base resins: from the standard PLA and ABS, to the more specialized TPU and HIPS. These materials can conduct electricity since the carbon they contain is graphitized – that is, the carbon atoms are arranged in a “honeycomb lattice”, giving it a crystalline structure. Each layer of this structure is called graphite, and the layers are collectively called graphene.

Not only does this structure give a rigidity and strength to the final print, but the nature of the bonds of the carbon atoms leaves a single free electron in each atom. This means that the material can transmit currents through these free electrons, albeit at a much slower rate compared to true conductive materials such as copper and iron.

Graphene is an incredibly thin material, making it appropriate for highly compact applications such as 3D printing filaments. Graphitic carbon has also been used as the main component of conductive inks.

Electrical Conductivity

Our Conductive Graphene PLA Filament offers a volume resistivity of 0.6 ohm-cm. Volume resistivity is the measure of a material’s resistance to electricity within a cubic centimeter of material. In order to determine if the material will work for your project, you will have to keep in mind that the resistivity will change depending upon your print. It is suggested that our filament can be used for the applications below.

High Strength

Conductive Graphene PLA Filament may also be used for applications which require superior strength to ABS and PLA.

Applications

Sensors

Conductive Graphene PLA Filament can be used to create capacitive (touch) sensors used in a wide range of electronics which you interact with on a daily basis; it is an excellent material for designing human interface devices! Capacitive sensing can also be used to measure proximity, position, humidity, fluid levels, and acceleration.

Projects include:

  • Gaming controllers
  • Digital keyboards
  • Trackpads
  • Drum Machines
  • MIDI controllers


Conductive Traces

Another application of Conductive Graphene PLA Filament is in the creation of electrically conductive circuitry for use in electronics. We love that 3D printing is a push-button process and we aim to keep it that way. Traditionally, 3D printing enthusiasts needed to add circuitry to their creation after it was printed in plastic, using copper wire; by offering a conductive filament, you can print graphene wiring simultaneously with your build process!

Projects include:

  • Interfacing computers, Arduino boards, and other components
  • Powering LED’s
  • Wearable electronics
