Applications
Where PET-CF excels
Warm and humid
Absorbs far less moisture than carbon-fibre nylon and stays heat-resistant up to 205 °C. Ideal for parts in warm or humid environments.
Load-bearing parts
Stiff and strong for brackets, mounts and mechanical assemblies, such as car accessories and fixtures.
Good to know
How to get the most out of your PET-CF
Hardened steel nozzle
Carbon fibre is abrasive. Use a hardened steel nozzle; 0.6 mm gives the best results. Stainless steel and 0.2 mm are not recommended.
Always dry it
Dry PET-CF for 8 to 12 hours at 80 °C and store it airtight with desiccant. That gives you the strongest prints.
Enclosed printer
Bambu Lab recommends an enclosed printer. On an open printer, your print cools faster and layer adhesion gets weaker.
Support material
For a smooth underside on overhangs, use Support for PA/PET as the interface layer.

Frequently asked questions
PET-CF or PETG-CF?
PETG-CF is easier to print and works in the AMS. PET-CF is more heat-resistant and absorbs less moisture, but needs dry filament and preferably an enclosed printer.
PET-CF or carbon-fibre nylon?
PET-CF absorbs far less moisture than nylon, so it stays more dimensionally stable in humid conditions. Nylon such as PAHT-CF, on the other hand, is more impact-resistant.
Does PET-CF work in the AMS?
No, PET-CF is not suitable for the AMS. Print it from the external spool holder.
Can I order it when it is out of stock?
No, you can only order what is actually in stock. The product page shows how many units are available. If it is temporarily unavailable, ask to be notified on the product page or get in touch with us.
How fast is delivery?
In-stock items are usually delivered within 1 to 3 working days in Belgium. Collection in Aalst is also possible.
