Graphene 3D printing filaments are high performing 3D printing materials that promise some exciting properties. Graphene is basically a thin layer of tightly packed carbon atoms, arranged in a honeycomb lattice structure. The graphene is integrated into the carrier polymer, often PLA, through a simple melt mixing method.
Graphene filaments are mechanically enhanced, their physical properties are similar to that of carbon fibre reinforced materials however graphene is much more easily integrated into a 3D printing filament. As well as its mechanical properties, graphene filaments have improved mechanical properties, dimensional stability, thermal stability, conductivity and abrasion resistance. Due to its robustness, it is also easy to post process graphene filaments. Graphene is a true multifunctional additive to a 3D printing filament.
