Bambu Lab PETG-CF 


Bambu PETG-CF combines the benefits of PETG and carbon fiber to deliver outstanding printing performance and enhanced mechanical properties. The improved formula minimizes nozzle clogging and clumping issues commonly associated with traditional PETG filament. The addition of carbon fiber reinforcement provides increased strength without compromising toughness, resulting in durable prints with excellent impact resistance. Additionally, Bambu PETG-CF boasts a glossy finish, adding a sleek and professional appearance to your printed models. Whether you're creating drone parts, racing models, or functional components, Bambu PETG-CF is the ideal choice for achieving high performance and aesthetic appeal.


Reduced Clumping and Stringing

Bambu PETG-CF has been specially formulated to overcome the common challenges of clumping and nozzle sticking that can occur during PETG printing. The modified formula ensures smooth and consistent extrusion, allowing for reliable and hassle-free printing. With this improvement, you can achieve high-quality prints with excellent adhesion between layers, reducing the risk of delamination or print failures. Bambu PETG-CF provides a seamless printing experience, making it an ideal choice for projects that require the unique properties of PETG combined with the added strength of carbon fiber reinforcement.

Carbon Fibre Texture

The inclusion of carbon fiber in Bambu PETG-CF introduces several desirable characteristics to the printed surface. One of these is the soft reflection that the carbon fiber imparts, giving the printed objects a more premium and refined appearance. Additionally, the carbon fiber reinforcement helps to minimize the visibility of layer lines, resulting in a smoother and more polished surface finish.

Tensile Strength 59 ± 4 MPa
Breaking Elongation Rate 10.4 ± 0.6 %
Bending Modulus 2890 ± 130 MPa
Bending Strength 83 ± 4 MPa
Impact Strength 41.2 ± 2.6 kJ/m²


Powerful XY Performance

The incorporation of carbon fiber in Bambu PETG-CF substantially improves the XY strength of the printed parts, providing them with increased structural integrity. The carbon fiber reinforcement reinforces the PETG matrix, enhancing its overall strength and reducing the risk of deformation or breakage under applied forces. Despite the added strength, the layer bonding of Bambu PETG-CF remains intact, ensuring that the printed objects maintain their dimensional stability and durability.


Smart Printing with RFID

With Bambu PETG-CF, all the essential printing parameters are conveniently embedded in an RFID chip. This RFID chip can be read by our AMS (Automatic Material System), eliminating the need for manual configuration and tedious setup steps.

Simply load the filament onto the printer, and the AMS will automatically detect the material and retrieve the corresponding printing parameters from the RFID chip. This streamlined process saves you time and effort, allowing you to start printing right away without the hassle of adjusting settings.

Say goodbye to manual parameter input and enjoy a more seamless and efficient printing experience with Bambu PETG-CF and our integrated AMS technology.

Increased Flexibility

Bambu PETG-CF stands out among other carbon fiber materials due to its exceptional toughness. The addition of carbon fiber reinforcement enhances the overall toughness of the PETG matrix, making it more resistant to fractures and failures under external stress and impact. This increased toughness ensures that the printed parts can withstand demanding applications and environments without compromising their structural integrity. Whether subjected to mechanical forces or impacts, Bambu PETG-CF exhibits a higher level of durability and resistance to failure, providing reliable performance for various functional and demanding 3D printing projects.
