Plastik Core PETG-CF 1.75mm Black SAMPLE 100g

Product detailed description

Fimanet PETG-CF is an improved version of classic PETG, to which chopped carbon fibers are added. The result is a material that prints almost as easily as regular PETG, but offers much higher dimensional stability, lower weight and a matte surface with a fine texture. It is an ideal choice for those who need strong parts without the complexity of printing nylon (PA).
Key Features
• High strength-to-weight ratio: Carbon fibers increase the stiffness (modulus of elasticity) of the material, which makes parts less prone to bending under load.
• Excellent dimensional stability: The addition of carbon minimizes heat shrinkage, which means almost zero warping even for large models.
• UV and water resistance: Unlike PLA or PA, PETG is naturally weatherproof, making it ideal for outdoor use.
• Professional matte look: Carbon fibers effectively diffuse light, almost completely masking the transitions between layers.
• Temperature resistance: Withstands temperatures up to approximately 75 - 80 °C, which is sufficient for most common technical applications.
Technical parameters and printing recommendations
Although easy to print, it requires specific hardware due to the abrasiveness of the fibers.
Parameter
Recommended value
Nozzle temperature
230 - 255 °C
Bed temperature
70 - 85 °C
Print speed
30 - 60 mm/s
Nozzle material
Hardened steel (carbon quickly wears away brass)
Nozzle diameter
0.4 mm and above are recommended (fibers can clog narrower nozzles)
Application examples
• Drones and robotics: Frames, arms and motor mounts where low weight and high rigidity are required.
• Functional Prototypes: Parts that must hold a precise shape and withstand mechanical pressure.
• Automotive Accessories: Holders, covers and interior elements (non-critical components).
• Tools and Fixtures: Assembly jigs and fixtures in the workshop.
Tips for working with Fimanet PETG-CF
1. Be careful with the nozzle: Carbon fibers act like a "saw". To maintain print accuracy, a hardened steel nozzle is essential.
2. Retractions: PETG-CF tends to string less than pure PETG, but it is still a good idea to have the retractions properly tuned.
3. Storage: Although PETG is more moisture resistant than Nylon, carbon fibers can bind moisture. For the best surface finish, we recommend storing in a dry place.
