Bambu PET CF

Bambu PET-CF is an innovative blend of robust PET and carbon fibre. The addition of carbon fibre improves the material’s hardness and mechanical strength, whilst maintaining the low warping and shrinkage typical of standard PET. The result is a filament with outstanding high-temperature resistance and an elegant, glossy finish.

Bambu PET-CF is characterised by its exceptional strength, heat resistance, dimensional stability and low moisture absorption. It is the ideal choice for applications where load-bearing structures or prints are used in environments with high temperatures and high humidity. With Bambu PET-CF, you get high-quality, durable prints that meet the most demanding requirements.

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), whilst PET-CF consists of polyethylene terephthalate (PET). The key difference: the "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, this also reduces its strength and stiffness.

What is the difference in application between PETG-CF and PET-CF?

PETG-CF is an extremely versatile base material which, thanks to its excellent toughness and ease of printing, is ideal for 3D printing everyday objects such as curved, folded and moving parts. It offers excellent impact resistance and withstands the demands of daily use.

In comparison, PET-CF contains a higher proportion of carbon fibres, resulting in significantly higher strength and temperature resistance. PET-CF is a professional-grade technical material specifically developed for use in more complex and demanding environments. It offers excellent rigidity and stability, even at high temperatures. Furthermore, PET-CF is less prone to warping and offers increased mechanical strength.

Reusable spool

Bambu Lab’s filament system is designed around an eco-friendly and reusable spool design, reducing plastic waste by at least 20%. Bambu Lab places great emphasis on sustainability, and the packaging material has been carefully selected to minimise the use of non-recyclable materials. Further information on the spool design can be found here. You can also print the spools yourself – the relevant files can be found via this link.
