Conductive Graphene Filament

Conductive Graphene Filament is a material made by Graphene 3D Lab, is specifically designed to allow you to 3D print electrically conductive components using almost any commercially available desktop 3D printer.

Principal properties:

• Electrical Conductivity: Conductive Graphene Filament offers a volume resistivity of 0.9 ohm x 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 Filament may also be used for applications which require superior strength to ABS and PLA.

Principal applications:

Sensors

Conductive Graphene 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 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

Note: Electrical resistance of a circuit must be considered in order to successfully use Conductive Graphene Filament in electronics applications; specifically, the filament is designed for low-current applications.

Electromagnetic and Radiofrequency Shielding

Superior conductivity offered with our Conductive Graphene Filament is not only excellent for 3D printed circuitry and sensors – it also means our filament is wholly capable of use in EMI and RF shielding applications critical for use in a range of industries, including:

• Telecommunications
• Hospital equipment
• Medical devices
• Enclosures and packaging
• Aerospace and Automotive

EMI/RF shielding is used to block the electromagnetic field and radio frequency electromagnetic radiation within a space; it is important to use EMI and RF shielding in a hospital, laboratory, or aerospace setting to protect against competing signals because they may lead to equipment giving false measurements. EMI/RF shielding accomplishes this by blocking AM, FM, TV, emergency services, and cellular signals. Conductive Graphene Filament is ideal for designing EMI/RF shields used in highly-customized items.

High-Strength mechanical and functional parts

Because Conductive Graphene Filament is mechanically stronger than ABS and PLA, it can be used to 3D print functional parts such as: hooks, hand-tools, and parts which require tooling, including drilling.

In the next video you can see the experiment create in the laboratory of a functional rechargeable battery, equivalent to the AA batteries capacity: Battery is charged, it puts its voltage to work together with other circuits and when it is spent can return to recharge. This battery can have any shape and even more integrated into any nook in the process of manufacture thus can fit the shape of different modern, increasingly small and complex devices, from sunglasses to watches or cameras of all kinds.

It is advisable to use a hardened steel nozzle or Olsson Ruby since the carbon fiber is quite abrasive and wears the brass nozzles.
