- Excellent Surface Finish - Fiberon™ PETG-rCF08 3D prints and renders parts with an attractive surface finish thanks to the PETG's excellent fluidity as a matrix material and the 8% carbon fiber reinforcement.
[1] Low moisture sensitivity does not describe whether the filament should be kept dry for optimal print quality. This description of moisture insensitivity is in the context of the end-use application where extremely moisture sensitive materials like PA6-CF see a significant reduction in mechanical properties as the part absorbs moisture. With PETG-CF moisture absorption is minimal and doesn't impact the mechanical properties of the part. For best printing results PETG-CF should still be kept dry during printing and storage.

The above are printing recommendations based on 0.4 mm nozzle. Please note ideal printing conditions may vary depending on your 3D printer setup. For high speed 3D printers, make sure to use a suitable printer and increase your extrusion temperature in order to use higher printing speeds.
Hardened nozzles such as hardened steel are less conductive than brass, so depending on your 3D printer, printing with a higher extrusion temperature may be required when using a wear resistant nozzle.
We highly recommend to use a wear resistant nozzle when printing Fiberon™ PETG-rCF08. Hardened steel offers much better wear resistance than brass. The second consideration it to keep PETG-rCF dry during printing and storage. See "Storage and Drying" details below for instructions to protect Fiberon™ PETG-rCF08.
Specific Printing Tips for Fiberon™ PETG-rCF08.
- Fiberon™ PETG-rCF08 is a very stiff filament due to its carbon fiber reinforcement. When not in use, please use tape to secure the filament tip to the spool the rather than attempting to bend the filament through the spool guide hole. During printing it is required to have a smooth feeding path to ensure optimal feeding. For example we recommend avoiding excessive bending in the filament guide system.
- Fiberon™ PETG-rCF08 can easily damage a brass nozzle after a few hundred grams of printing. Nozzles come in many different materials from soft to hard and the heat conductivity of a nozzle can change depending on what material it is made of. Hardened steel is more abrasion resistance than brass or a nickel plated nozzle.
- Inter-layer strength can depend significantly on your extrusion temperature which is a result of your printing speed, nozzle type and hot end. A higher nozzle temperature / extrusion temperature can offer significant benefits in regards to inter-layer strength. When printing Fiberon™ PETG-rCF08 at low temperature (240 ˚C) on a general desktop 3d printer, it is recommended to use a hardened nickel-coated brass nozzle which offers better thermal conductivity than hardened steel or a high flow hot-end to ensure better melt performance.

Compatibility
Fiberon™ PETG-rCF08 has been engineered so users can print strong carbon fiber filled parts on a wide range of 3D printers. As the carbon fiber in this material is highly abrasive we recommend customers first check that their 3D printer is equipped to print abrasive materials before purchasing this product.
Aside from wear resistance, there are a few important considerations for this material that we recommend.
Reinforced filaments tend to be much stiffer than other standard filaments and this can cause problems when passing the filament through a printer’s feeding system. For a steady and uninterrupted flow of filament, it is recommended to take extra care and make sure your filament guide system is smooth and with minimal bends. Brass nozzles give a better thermal conductivity than hardened nozzles such as stainless steel. Depending on your 3D printer, printing with higher extrusion temperatures may be required when using specialty nozzles to ensure the correct extrusion temperature is achieved.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer. Slicer experience and setting adjustment is always required to get the most out of a material. Before jumping into an ambitious project we always recommend printing some known calibration tests to build or make adjustments to the filament profile.
Technical Data & Safety Data Documents
We have full MDS and technical data sheets for Fiberon™ PETG-rCF08 and all other Fiberon filaments from Polymaker. Contact us to enquire!
The typical values presented in Polymakers data sheet are intended for reference and comparison purposes only. Due to the nature of 3D printing they should not be used for design specifications or quality control purposes.
STORAGE & DRYING
All plastics are hygroscopic meaning they absorb moisture from the air which can affect printing quality and strength of printed parts. How quickly this absorption occurs depends on the material and your environment. Fiberon™ PETG-rCF08 filaments are dried and packaged in a vacuum sealed bag with desiccant to ensure the best printing quality. When not in use Fiberon™ PETG-rCF08 should be stored away from sunlight and sealed in the packaged resealable bag.
Although filaments can be dried, drying will speed up the aging process of the plastic. Preventing the filament from absorbing moisture in the first place is the best solution to keep your filament working to its maximum potential. For long term storage we highly recommend storing in a sealed container with dry desiccant that reduces the relative humidity to 10-20% RH.
In-house we manage our filaments with Polymakers PolyDryer™ which keep offers best-in-class sealing to protect filaments from absorbing moisture
If you hear popping sounds and notice that the surface quality of your print is uneven or the colour is not consistent, this is a likely indicator that the filament has absorbed too much moisture. Spools of Fiberon™ PETG-rCF08 can be dried with Polymaker PolyDryer™ using power level 2 for 6 hours.. Alternatively if you have a convection oven that is accurate at low temperatures, users can dry filament in a preheated convection oven at 65˚C for up to 3 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.
FAQ
Q: Should PETG-rCF be annealed?
A: No, due to the amorphous nature of PETG, annealing PETG-r-CF is not required and will not provide added thermal or mechanical properties. This is in contrast to PET-CF which is semi-crystalline and does see benefit from annealing.
Q: Do I need an enclosure to print PETG-rCF?
A: As a general rule, no an enclosure is not required, however this is really dependent on the ambient room temperature, size, geometry and infil density of your parts. When printing without an enclosure it is important to keep the printer away from cold drafts that could impact the print.
Q: Should I rewind this filament if I want to use it with a different spool?
A: We strongly advise against tampering with the product by rewinding. See our article for full details about the risks. All Polymaker filaments are wound with tension but without strain. Rewinding completely rearranges the curvature of the winding and this strain over time can cause most plastics to catastrophically break. If for some reason your printer is locked into fitting less than standard sized spools, there may be safe printable adaptors or external mounting solutions available.

Care Instructions
Care Instructions
PLA
Temperature:
Keep it cool! PLA starts to soften at around 60°C (140°F), so avoid placing it near heat sources or leaving it in hot cars.
Sunlight:
Prolonged direct sunlight can cause fading and potential deformation. Try to keep it out of long sun exposures.
Cleaning:
Gently wash with warm water and a bit of mild soap using a soft cloth. No harsh scrubbing, please!
Handling:
Handle with care—avoid excessive bending or dropping it, as PLA is rigid and can crack or break.
Storage:
Store in a cool, dry place to maintain its shape and longevity.
TPU
Temperature:
TPU is built to be flexible, but still avoid extreme or prolonged heat. It’s more resilient than PLA, but unnecessary heat can still degrade it over time.
Sunlight:
Try not to leave TPU items in direct sunlight for too long, as UV rays can fade the colors and slowly affect the material quality.
Cleaning:
Just like PLA, a quick clean with warm water and mild soap works great. Use a soft cloth and don’t be too rough.
Handling:
Enjoy its flexibility! However, even though TPU can bend, continuous stretching or heavy impacts might wear it out faster.
Storage:
Keep it in a cool, dry spot away from harsh elements to maintain its flexibility and appearance.
