Bambu PET-CF
Bambu PET-CF is a blend of strong PET and carbon fibre. The carbon fibers improve stiffness and mechanical strength while helping to maintain the low strain and shrinkage levels of regular PET. Bambu PET-CF has excellent resistance to high temperatures and a soft shiny appearance. Excellent strength, heat resistance, dimensional stability and low moisture absorption make Bambu PET-CF an ideal choice for load bearing structures or prints used in high temperature and humidity environments.
Low moisture absorption
Under conditions of saturated water absorption, the strength and hardness of PET-CF have little loss, making it suitable for prints used in high humidity environments.
Normal PA-CF
Loading weight: 1 kg
Bambu PET-CF
Loading weight: 1 kg
The test patterns are 220 mm span and 3 mm thick in the unloaded condition.
High dimensional stability
Due to the creep and deformation resistance of PET-CF, the prints can achieve excellent matching accuracy.
Specimen size (L*W*H): 240*8*15 mm³
Fill density: 60%
Exceptional thermal resistance
– Specimen size (L*W*H): 95*10*4 mm³
– Test conditions: The specimens are placed in an oven at 70 °C and 150 °C for 0,5 hours.
* As a crystalline material, PLA deforms significantly only once the temperature exceeds the melting point (about 155 °C).
Print Setup
Nozzle of hardened steel 0,6 mm (recommended)
Nozzle of hardened steel 0,4 mm / 0,8 mm (possible)
Enclosed printer (recommended)
Open frame printer (Possible)*
AMS is NOT compatible
*The bonding of the layers of some prints may become weak due to supercooling.

Frequently Asked Questions
What is the difference between PET-CF and PETG-CF?
The main difference between PET-CF and PETG-CF lies in their base material. PETG-CF is a reinforced material produced by adding carbon fibres to glycol-modified polyethylene terephthalate (PETG), whereas PET-CF is to polyethylene terephthalate (PET). The key difference‘G‘ in PETG stands for glycol. PETG is a glycol-modified version of PET that contains small amounts of glycol as a comonomer. The addition of glycol to PETG reduces its crystallinity and makes it more transparent. However, it also reduces its strength and stiffness.
The difference in the application of PETG-CF and PET-CF?
PETG-CF is a versatile base material that is suitable for printing everyday items such as bent, folded and moving parts due to its excellent strength and ease of printing. PET-CF, in contrast, contains a higher amount of carbon fibre and is significantly stronger and more temperature resistant than PETG-CF. PET-CF is a professional grade engineering material that is suitable for use in more complex and demanding environments.
What is PET-CF used for?
Due to its dimensional stability and lower water absorption rate, PET-CF is a better choice than nylon for printing functional parts used in high humidity environments. Also, its resistance to high temperatures and low deformation make it suitable for printing mechanical assembly parts such as automotive accessories and fixtures.

Printing tips
– Drying conditions: 80℃ for 8 hours. PET-CF is highly sensitive to humidity. To achieve optimum print performance, additional drying before use and after storage is recommended. For more details, please refer to:Filament Drying Instructions in WIKI.
– To prevent moisture absorption from the material, it is recommended that an airtight storage container with desiccant be used during printing. For more details, please see:WIKI Printing Tips for Engineering Materials.
