Prografen Filament
Graphene-reinforced PLA and PETG from Poland. -- products tracked with live pricing.
Last updated: March 2026
Prografen is a Polish manufacturer specializing in graphene-reinforced filaments. Their Graphene Strong and Graphene Light formulations add graphene to standard PLA and PETG, improving layer adhesion, rigidity, and surface quality. Premium pricing but genuinely novel material properties.
Available through 3DJake in the UK, Germany, and France. Prografen occupies a niche position in the market — these are specialty filaments for users who want measurably better mechanical properties without switching to engineering-grade materials or dealing with abrasive additives like carbon fiber.
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice. When added to filament, it improves interlayer bonding, increases thermal conductivity (helping with even cooling), and enhances surface finish. Unlike carbon fiber, graphene particles are not abrasive — you can use a standard brass nozzle without accelerated wear.
Product Lines
Prografen's PLA Graphene line includes both Graphene Strong and Graphene Light formulations. Graphene Strong maximizes rigidity and layer adhesion, while Graphene Light offers a balance between enhanced properties and easier printability.
These print at standard PLA temperatures with no special hardware required. The graphene additive gives prints a subtle dark tint and noticeably smoother surface finish compared to regular PLA.
PETG Graphene combines PETG's natural chemical resistance and flexibility with graphene's enhanced layer bonding and thermal conductivity. The result is a functional material that's tougher and more rigid than standard PETG.
Prints at standard PETG temperatures. The graphene additive helps with one of PETG's common issues — layer adhesion — making it a practical upgrade for functional parts that need to hold up under stress.
