PCTG filament - the best alternative to PET-G in 3D printing

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.

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.
