Description
Bambu Lab PET-CF Filament 1.75mm – 500g
- Dry out before use
- AMS NOT compatible
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.

Printing Tips
• Bambu PET-CF needs proper drying before printing: recommended drying temperature is 80 ℃ for 5 hours in a blast drying oven, or 90 ℃ for 10 hours on heat bed. (Do not exceed 100 ℃ because the spool may melt).
• To prevent the material from absorbing moisture, it is recommended to use an airtight storage container with desiccant during printing.
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.
