When you need parts that are sturdy, stable, and professional‑looking, PETG‑CF filament from Siraya delivers.
This advanced blend of PETG and finely chopped carbon fibers gives prints a boost in stiffness, dimensional accuracy, and surface quality.
The carbon fibers reinforce the PETG base, making it more rigid and resistant to deformation while keeping it slightly lighter than standard PETG.
The result is prints that perform well and feature a smooth, matte finish that hides layer lines beautifully.
Why PETG‑CF Filament Is a Game Changer
PETG‑CF filament is designed for makers who need reliable strength and precision. The carbon fiber reinforcement reduces shrinkage and warping, ensuring your prints hold their shape even under stress.
- ✅ Higher stiffness and strength than regular PETG
- ✅ Matte surface finish for a professional appearance
- ✅ Low shrinkage for improved dimensional accuracy
This filament is an excellent choice for functional prototypes, mechanical parts, and performance components that need to stay stable and strong.
Practical Uses for PETG‑CF Filament
PETG‑CF filament is made for real‑world applications where durability matters. Its carbon fiber blend makes it ideal for parts that face vibration, pressure, or repeated use.
- ✅ Perfect for robotics, drones, and automotive parts
- ✅ Maintains shape in moderate heat and mechanical stress
- ✅ Lightweight yet strong for high‑performance designs
From machine brackets to tool mounts, PETG‑CF filament helps you create parts that last longer and perform better.
Built for Precision and Smooth Performance
Siraya’s PETG‑CF filament offers excellent print consistency and a clean, matte texture that feels as good as it looks.
The carbon fibers improve rigidity and also reduce stringing, helping you achieve cleaner surfaces with less post‑processing.
- ✅ Strong layer adhesion for dependable prints
- ✅ Minimal stringing and stable extrusion
- ✅ Balanced performance between toughness and printability
If you’ve had issues with standard PETG bending or warping, PETG‑CF provides the extra stability you need for professional‑grade results.
Lightweight Durability That Delivers
PETG‑CF filament gives your prints the mechanical strength of reinforced materials while keeping weight slightly lower than standard PETG. It’s designed for functional parts that need to be both strong and efficient.
- ✅ Slightly lighter than PETG with higher stiffness
- ✅ Maintains form under stress and temperature changes
- ✅ Ideal for functional prototypes and final‑use parts
This makes PETG‑CF a smart upgrade for anyone building performance‑driven or structural components.
Reliable Printing with PETG‑CF Filament
Printing with PETG‑CF filament is straightforward with the right setup. It works best with a hardened steel or ruby nozzle to handle the abrasive carbon fibers and a heated bed to ensure good adhesion.
- ✅ Prints smoothly at 240–265 °C
- ✅ Heated bed recommended (75–85 °C)
- ✅ Works with most open‑material 3D printers that have an all‑metal hotend
Once tuned, PETG‑CF filament produces consistent, strong prints with minimal warping, perfect for both hobby and professional use.

Frequently Asked Questions on PETG‑CF Filament
What is PETG‑CF filament?
PETG‑CF filament is a blend of PETG plastic and chopped carbon fibers. This mix increases stiffness, reduces warping, and gives prints a matte, professional finish. It’s ideal for functional parts that need strength and precision.
Is PETG stronger than PETG‑CF?
No, PETG‑CF is stronger and more rigid than standard PETG. The carbon fibers boost stiffness and reduce flex under load. This makes it better for mechanical or structural parts that require durability.
Is PETG‑CF easy to print?
PETG‑CF is relatively easy to print with proper settings. It works best with a heated bed and all‑metal hotend for stable extrusion. Once tuned, it offers clean, reliable prints with minimal warping.
Does PETG‑CF require a special nozzle?
Yes, PETG‑CF should be printed with a hardened steel or ruby nozzle. The carbon fibers are abrasive and can wear out brass nozzles quickly. Using a durable nozzle ensures consistent results and longer nozzle life.
