Product description
Professional Lab PETG CF Blue 1 kg
Professional Lab PETG CF Blue is a technical composite filament based on PETG with an admixture of carbon fibers (CF). It combines ease of setup like regular PETG with significantly higher stiffness, strength, and better dimensional stability, making it a great choice for professional and advanced hobby use.
The Blue shade with a fine carbon texture gives prints a technical and modern look, while carbon fibers help mask layers and minor surface imperfections.
Usage and typical applications
- functional mechanical parts and components (holders, grips, covers, reinforcements)
- technical prototypes and assembly fixtures
- parts exposed to dynamic stress and vibrations
- partially temperature-resistant components for the workshop, car interior parts, etc.
- structural elements where higher stiffness compared to classic PETG is desired
Key features
- Composite PETG with carbon fibers (CF) – increased stiffness and strength compared to standard PETG.
- Excellent dimensional stability – minimal warping and deformation, suitable for precise technical parts.
- Good chemical and moisture resistance typical for PETG – suitable even for more demanding environments.
- Matte, technical surface – carbon fibers help hide layers and minor defects.
- Reliable Professional Lab quality – stable diameter, consistent color, and mechanical properties.
- Universal diameter compatible with most FDM/FFF 3D printers.
Warning: Due to the carbon fiber content, the filament is abrasive. For long-term printing, it is recommended to use a hardened steel, quenched, or ruby nozzle to prevent rapid wear of a standard brass nozzle.
Recommended printing parameters
Specific settings may vary by printer, nozzle, and cooling; use the values below as a starting point:
| Parameter | Recommended value* |
|---|---|
| Nozzle temperature | 230–255 °C |
| Bed temperature | 80–95 °C |
| Print speed | 40–70 mm/s |
| Cooling | low to medium (0–40 %) |
| Enclosed print chamber | recommended, but not necessary |
*The recommended range is based on Professional Lab PETG data sheets and usual settings for PETG CF.
Tips for successful PETG CF printing
- Use a durable nozzle Carbon fibers significantly abrade the filament – a standard brass nozzle can wear out quickly and lose its diameter.
- Slightly increase the temperature compared to classic PETG The filler can slightly increase melt viscosity; a higher nozzle temperature will help with layer bonding.
- Do not be too aggressive with cooling For maximum strength, reduce fan intensity – layers will bond better.
- Ensure dry filament PETG tends to absorb moisture, which in composites manifests as microbubbles and a poorer surface. If in doubt, dry the filament before printing.
- Better bed adhesion Print on PEI, glass, or a textured bed with a suitable adhesive (glue, special spray) to prevent corner peeling.
Who is Professional Lab PETG CF suitable for
- Advanced users and professionals who need stronger and stiffer parts than those from regular PETG or PLA.
- Owners of workshop and semi-professional printers who want to increase the durability of their prints without switching to more demanding materials (nylon, PEEK, etc.).
- Hobby designers who experiment with functional prints and appreciate the better mechanical properties of composite filaments.
Summary
Professional Lab PETG CF Blue is a reliable technical filament for more demanding functional prints. It offers better strength, stiffness, and dimensional accuracy than standard PETG, while maintaining relatively comfortable printing. The blue color with carbon texture gives your projects a professional, technical look, and thanks to carbon fibers, layers will be less visible.
Key features:
- Composite PETG filament with carbon fiber admixture for higher strength and stiffness.
- Excellent dimensional stability and minimal warping – suitable for precise technical parts.
- Matte technical surface in a blue shade with a fine carbon texture.
- Good chemical and moisture resistance, typical for PETG materials.
- Compatible with most FDM/FFF 3D printers with a filament diameter of 1.75 mm.
- Suitable for mechanically stressed and functional parts, fixtures, and structural prototypes.
- Reliable Professional Lab quality with stable diameter and consistent properties.
- Abrasive composition – when used, replacing the nozzle with a hardened or quenched one extends its lifespan.
