- Graphene-enhanced for superior conductivity and improved mechanical properties
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.
Conductive Graphene PLA Filament may also be used for applications which require superior strength to ABS and PLA.
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.
- Gaming controllers
- Digital keyboards
- Drum Machines
- MIDI controllers
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!
- Interfacing computers, Arduino boards, and other components
- Powering LED’s
- Wearable electronics
Note: The electrical resistance of a circuit must be considered in order to successfully use Conductive Graphene PLA Filament in electronics applications; specifically, the filament is designed for low-current applications.
Electromagnetic and Radiofrequency Shielding
The superior conductivity offered with our Conductive Graphene PLA 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:
- 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 PLA Filament is ideal for designing EMI/RF shields used in highly-customized items.
High-Strength mechanical and functional parts
Because Conductive Graphene PLA 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.
Our filament is shipped in a vacuum-sealed package with a desiccant packet. Conductive Graphene PLA Filament should be stored in a dry environment away from dust and other particles. User should avoid extended exposure to moisture. We recommend storing in an enclosed container with a desiccant packet. 3D printers, especially their nozzles, should always be maintained, and should be cleaned before and after use of Conductive Graphene PLA Filament to avoid complications during printing. Users are also instructed to wash their hands before and after use of Conductive Graphene PLA Filament.
Conductive Graphene PLA Filament softens at high-temperatures (~50°C) and is designed to be used with prints intended for room-temperature operation; it is intended for low-voltage and low-current projects only. Do not exceed 12 volts and avoid using the filament for power supply’s that exceed 100 mA. Resistivity of one meter of 1.75 mm filament is 4 kOhm’s. Keep in mind that a major factor influencing resistivity is contact resistivity, so shortening the length of the trace will not linearly correlate to a decrease in resistivity.The intrinsic properties of our Conductive Graphene PLA Filament is such that it should not be left idle (as in not extruding or printing) in a heated printer nozzle. It may expand and cause blockage. After the printing is complete, remove filament from the nozzle promptly.
If using this material for dual-extrusion printing, we recommend using in conjunction with PLA.
A 3D printer nozzle larger than 0.5 mm is suggested for use of Conductive Graphene PLA Filament.
