PCTG+GF filament is our latest product for 3D printing enthusiasts, combining the strength and versatility of modern copolyester with the unique properties of glass fiber. It is a technical filament with high impact strength, ideal for advanced projects where typical polymers are not enough.

Glass fiber (10%) adds unique capabilities to the filament, creating a product with higher strength and stiffness, while remaining resistant to external conditions and chemicals. The properties of the filament make it ideal for printing machine parts, tools or outdoor applications.

Fiberlogy PCTG+GF is a guarantee of trouble-free printing. Low shrinkage, excellent table adhesion and the ability to print in 3D printers not equipped with a closed chamber, make this filament can be used on any printer. Its users will also appreciate the matte, rough finish, giving the models a perfect look.


  • PROTOTYPING: functional prototypes, specialized tools, low-volume production
  • AUTOMOTIVE: elements of covers, connectors, housings of electronic components
  • ELECTRONICS: enclosures with increased resistance to impacts, chemicals and temperatures

How to print?

The following parameters are only suggested print settings for this material. To ensure the best print quality, it is necessary to choose the appropriate settings for a specific printer and printing conditions.


Nozzle Temperature 250-270°C
Bed Temperature 90-110°C
Closed chamber not required
Fan 0-25%
Flowrate 90-100%
Printing Speed 35-60 mm/s
Surface masking tape, PVA glue, hairspray
Retraction (direct) 1-2 mm
Retraction (bowden) 3-5 mm
Retraction Speed 20-45 mm/s
Drying conditions 60°C / 4h
Notes Due to the strong adhesion to the bed, it is not recommended to print directly on its surface or on glass. This can lead to damage. We recommend using a masking tape.
