PCTG filament - the best alternative to PET-G

PCTG filament belongs to the same family of polyesters as the increasingly popular PET-G. Compared to its more popular counterpart, PCTG offers increased impact strength, temperature resistance and clarity, making it an excellent alternative to PET-G. This filament does not require a heated chamber, which makes it ideal for use with home printers. It ensures high dimensional stability, while low shrinkage prevents the model from cracking. This makes it an easy-to-print material, even for people without a lot of experience in 3D printing.

PCTG is characterized by a much higher impact strength compared to similar materials (e.g. Easy PET-G filament). It achieves results in the region of 90 kJ/m2 (PET-G: 5-8 kJ/m2) in the Izod test (notched sample). PCTG also withstands higher temperatures (up to 76°C).

Fiberlogy PCTG filament is recyclable and approved for contact with food *. The material is BPA free.

PCTG properties:

  • high impact strength (up to 20 times greater than PET-G)
  • high chemical resistance
  • high optical transparency
  • easy to print – dimensional stability and low shrinkage
  • suitable for contact with food – BPA free

How to print PCTG?

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 < 100 mm/s
Surface masking tape, PVA glue, hairspray
Retraction (direct) 1-2 mm
Retraction (bowden) 4-6 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.
