The long awaited Conductive Graphene Filament from Graphene 3D Lab Inc. (GGG) hit the market today. 

On February 2, the company announced that it had received and assembled an industrial scale thermoplastic extruder line at their Calverton, NY facility to produce their long awaited graphene filament.

The filament incorporates highly conductive nano-carbon platelets to enhance the properties of PLA, a widely used thermoplastic. Incorporating graphene into a commercial thermoplastic filament opens up the possibilities of 3D printing conductive traces within a 3D printed part. Though by no means does this mean that 3D printers can all of the sudden print complex electronic devices, it does mean that people can begin to experiment and design simple 3D printed electronic devices, ready-made for additional components.

Conductive Graphene 3D Filament Specs:

  • Volume Resistivity: 1 ohm-cm
  • Color: Black Diameter: 1.75 mm
  • Size: 200 grams
  • Cost: 65$ per spool

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 the print or circuit design.

The conductive filament will be sold on Graphene 3D’s recently launched e-commerce platform, Black Magic 3D, which will also be the trade name for all current and future Graphene 3D filaments.
