Fiberon™ PPS-CF10 is a carbon fiber reinforced PPS (Polyphenylene sulfide) filament, with minimal warping during printing and no need for a heated chamber. With exceptional mechanical strength, high heat resistance, chemical resistance, V0 flame retardancy, and moisture insensitivity, it's specifically designed for professionals operating in extreme conditions.

^[1] Fiberon™ PPS-CF10 displays the best mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallization during the printing process, an additional step is required: Annealing. PPS-CF10 can be annealed in the oven at 125˚C for 16 hours.
^[2] Moisture insensitivity 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 PPS-CF moisture absorption is minimal and doesn't impact the mechanical properties of the part. For best printing results PPS-CF should still be kept dry during printing and storage.

Technical Data

All PPS-CF specimens were printed with 350°C nozzle temperature, 90°C bed temperature, cooling fan OFF and samples were annealed after printing at 125°C for 16h. Samples were printed with 100% infil, 2 shells and 3 top & bottom layers.

Printing Settings

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™ PPS-CF10. Hardened steel offers much better wear resistance than brass. The second consideration it to keep PPS-CF dry during printing and storage. See "Storage and Drying" details below for instructions to protect Fiberon™ PPS-CF10.

Specific Printing Tips for Fiberon™ PPS-CF10.

• Fiberon™ PPS-CF10 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™ PPS-CF10 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™ PPS-CF10 at low temperature (310 ˚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.

Annealing  PPS-CF10

For the best mechanical performance it is highly recommended to anneal parts printed in Fiberon™ PPS-CF10. Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. Fiberon™ PPS-CF10 displays outstanding mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallization after the printing process and annealing is required to complete this step.

We strongly recommend 125°C, 16h annealing to achieve the best performance of the material.

Specification

Compatibility

Fiberon™ PPS-CF10  has been engineered so users can print strong carbon fiber filled parts on printers capable of reaching up to 350°C. 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.

To get the best mechanical and thermal properties out of this material, annealing is strictly recommended. Please read information further above regarding annealing steps.

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.

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™ PPS-CF10 filaments are dried and packaged in a vacuum sealed bag with desiccant to ensure the best printing quality. When not in use Fiberon™ PPS-CF10 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™ PPS-CF10 can be dried with Polymaker PolyDryer™ using power level 3 for 18 hours.. Alternatively if you have a convection oven that is accurate at low temperatures, users can dry filament in a preheated convection oven at 100˚C for up to 10 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: Do I need to anneal PPS-CF?
A: It is ideal to anneal parts printed in PPS-CF if you are after the best mechanical properties, however PPS-CF10 has good performance after printing and can be used without annealing for some applications. PPS is a semi-crystalline material and its thermal and mechanical properties are directly tied to its crystallisation, a process in which the polymer chain aligns to create tightly packed regions that improve heat resistance and strength. Annealing is an important step to complete the crystalline process and ensure consistency and high performance. The technical data is based on samples that have been annealed.

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.
