  • Easy to print with dimensional stability, and low shrinkage making this material great for beginners as well as more advanced professionals
  • Suitable for contact with food* (Pure TR), and BPA free

Samples Collection:

You can also order an PCTG sample to test from our Samples Collection ; create a custom sample pack to compare different options to find the exact right material for your project.


PCTG 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. PET-G). 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 is recyclable and approved for contact with food *. 

This material is also BPA free.

* applies to the Pure TR version
