Conductive Graphene Filament was tested using a direct drive 3D printing extruder. We do not guarantee that Conductive Graphene Filament will be compatible with non-direct drive 3D printers, such as delta models.


The filament is shipped in a vacuum-sealed package with a desiccant packet. Conductive Graphene 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 Filament to avoid complications during printing. Users are also instructed to wash their hands before and after use of Conductive Graphene Filament.

Conductive Graphene 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 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.
