Prografen ReFill PLA Graphene Strong Jet Black, 1,75 mm / 1000 g

Prografen PLA Graphene Strong is the next-generation filament: made from biodegradable PLA and enriched with 5% graphene flakes (EFG), it offers exceptional mechanical strength, abrasion resistance and flexibility. The innovative material enables ultra-fast printing with impressive precision and is therefore ideal for demanding projects where quality and efficiency are paramount.

Thanks to an exceptionally high melt flow rate (MFR – 44 g/10 min) and minimal shrinkage, Prografen PLA Graphene Strong impresses with excellent dimensional stability. And the best part? It can be easily printed with standard brass nozzles without confronting you with excessive nozzle wear – a clear advantage over carbon fiber-reinforced alternatives.

This filament is designed to achieve printing speeds of over 1000 mm/s, making it one of the fastest printing materials on the market. At the same time, the graphene reinforcement provides exceptional lightness and stability, making it ideal for technical and industrial applications.

► Note: Compared to carbon fibre materials, graphene particles are non-abrasive, which means they can be processed with standard nozzles.

This ReFill is a spoolless PLA filament wound on a cardboard core. It is compatible with the reusable Bambu Lab spools and the self-printed Spectrum ReFill spools* and does not require any additional adapters. This sustainable solution reduces plastic waste and is also extremely inexpensive.

* Here you can find STL files for the ReFill spools for printing yourself.
