Bambu Lab PPS-CF Filament 1.75mm - 750G
Bambu PPS-CF
PPS-CF is a composite material made from carbon fiber-reinforced polyphenylene sulfide. The combination of PPS resin and carbon fiber gives PPS-CF exceptional properties, including excellent resistance to solvents, corrosion, heat, and flames. Additionally, it offers superior strength, stiffness, and dimensional stability, making it a specialized engineering plastic that meets the demands of unique and challenging applications.
Ultra-High Heat Resistance
PPS-CF boasts a heat deflection temperature of up to 264°C under 0.45 MPa and can continuously operate at temperatures exceeding 200°C. This significantly outperforms normal PA-CF materials, which have maximum temperatures around 190°C and 120°C. Its exceptional heat resistance ensures outstanding creep resistance, making PPS-CF ideal for demanding industrial environments and applications.
Superior Flame Retardancy
PPS-CF achieves a UL-94 V-0 flame retardant rating, offering superior safety and reliability in critical areas such as electronics and automotive components. PPS-CF provides long-lasting durability and peace of mind even in the most demanding environments.
Unmatched Mechanical Properties
Combining the stiffness of PPS polymers with the reinforcing power of carbon fiber, PPS-CF offers exceptional stiffness, bending strength, and tensile strength. Its superior dimensional stability and resistance to warping ensure that large-scale prints maintain precision and avoid deformation during the printing process, making it perfect for high-precision applications.
Solvent and Chemical Resistance
PPS-CF offers outstanding solvent and chemical resistance, second only to PTFE (Teflon). It remains virtually insoluble in any solvent below 200°C and exhibits exceptional resistance to acids, bases, and salts under normal conditions. This makes PPS-CF the ideal choice for challenging environments where chemical stability is critical.
Ultra-Low Water Absorption
With an extremely low moisture absorption rate of just 0.05%, PPS-CF ensures that its mechanical and thermal properties remain stable even in humid conditions. Unlike normal PA-CF, which can soften and degrade when exposed to moisture, PPS-CF maintains its strength and durability, making it the superior option for applications requiring high moisture resistance.

Printing Tips
Bambu PPS-CF Printing Guidelines:
- Nozzle Temperature: Recommended range is 310 to 340°C.
- Chamber Temperature: Recommended range is 60 to 90°C.
- Tip: Using higher values within these ranges can enhance the mechanical properties of the printed parts, especially in the Z-direction.
Drying Recommendations:
- Drying Temperature:
In a blast drying oven: 100°C to 140°C for 8 to 12 hours.
On an X1 printer's heatbed: 110°C to 120°C for 10 to 12 hours (less effective than a blast drying oven).
- Important Note: Higher temperatures within the drying range yield better results, but do not exceed 160°C to avoid damaging the spool.
- Additional Information: For more details, refer to Printing tips for Engineering materials on WIKI.
Storage Tips:
- Storage Condition: To prevent the filament from absorbing moisture, use an airtight storage container with desiccant during printing.
- For Further Details: Please refer to Printing tips for Engineering materials on WIKI.
Annealing Prints:
- If you need to anneal the prints, please refer to the Technical Data Sheet (TDS) and the WIKI section Work After Printing Finished.
