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.

High dimensional stability

Due to the creep and warping resistance of PET-CF, prints can achieve excellent matching accuracy.

Printing setup

• 0.6 mm Hardened Steel Nozzle (Recommended)
• 0.4 mm / 0.8 mm Hardened Steel Nozzle (Capable)

• Enclosed printer (Recommended)
• Open frame printer (Capable)*

AMS NOT compatible

*Layer bonding of some prints may become low due to overcooling.

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 Bambu Lab's 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 Bambu Lab's Wiki.
