Description
Bambu PET-CF
Bambu PET-CF is a blend of tough PET and carbon fiber. Carbon fiber improves hardness and mechanical strength, while still help maintain the low warping and shrinkage of ordinary PET. Bambu PET-CF has excellent high temperature resistance and a soft glow appearance. Its 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 humid environments.
Low moisture absorption
In saturated water absorption conditions, the strength and stiffness of PET-CF have small losses, 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 models have a span of 220 mm and a thickness of 3 mm in unloaded state.
High dimensional stability
Due to the creep and warping resistance of PET-CF, prints can achieve excellent matching accuracy.
Specimens size (L*W*H): 240*8*15 mm
Infill density: 60%
Exceptional thermal resistance
Specimen size (L*W*H): 95*10*4 mm
Test conditions: Specimens were put in an oven at 70 C and 150 C respectively for 0.5 hour.
* As a crystalline material, PLA will significantly deform only after the temperature exceeds its melting point (around 155C).

Frequently Asked Questions
What is the difference between PET-CF and PETG-CF?
The primary difference between PET-CF and PETG-CF lies in their base material. PETG-CF is a reinforced material made by adding carbon fiber to glycol-modified polyethylene terephthalate (PETG), while 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 co-monomer. 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 application between PETG-CF and PET-CF?
PETG-CF is a versatile basic material that is suitable for printing everyday items, such as bent, folded, and movable parts, due to its excellent toughness and ease of printing. PET-CF, in contrast, contains a greater amount of carbon fiber and is significantly stronger and more temperature resistant compared to 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 high-temperature resistance and low warping make it suitable for printing mechanical assembly parts, such as automotive accessories and fixtures.

Printing Tips
Drying conditions: 80 for 8 hrs. PET-CF is highly sensitive to humidity. To achieve optimal printing performance, it is recommended further drying before use and after storage. For more details, please refer to:Filament drying instructions on WIKI.
To prevent the material from absorbing moisture, it is recommended to use an airtight storage container with desiccant during printing. For more details, please refer to:Printing tips for Engineering materials on WIKI.
