BigRep’s PET-CF is an engineering-grade filament for high-strength additive manufacturing applications. With exceptional dimensional stability and low moisture absorption, it’s the perfect material for printing in industrial environments. Capable of producing exceptionally strong, stiff parts with a fine surface finish and heat resistance up to 100 °C, this material is ideal for functional, performance applications.

PET-CF is a reliable and easy to use material for environments with limited control like a factory floor.
