Prografen Graphene PLA filament is a combination of high-quality PLA plastic and graphene. This filament has high strength and flexibility, as well as a low coefficient of thermal expansion. It is an ideal choice for those who are looking for a filament with high strength, but with an easy-to-machine material. Graphene imparts similar properties to carbon fiber, but does not burden the user with the need to replace the nozzle with a cured one or one with a larger diameter. Graphene does not clog the nozzle like fiber does, which allows for a maintenance-free start to the product. PLA PROGRAPHEN GRAPHENE is a black colored material for general use. It is a high molecular weight biopolymer based material. In addition to the standard properties that characterize PLA filaments, the addition of graphene increases the flexibility of the filament and its tensile strength. Printed parts have higher abrasion resistance, are characterized by a very good coefficient of friction of printed parts, the filament can be easily extruded through standard nozzles ensuring long life, improve the dimensional stability of the printed parts.
