PPS – CF – Black – black – Bambu Lab
Bambu PPS-CF
PPS-CF is a composite material made of polyphenylene sulfide reinforced with carbon fibers. The combination of PPS resin and carbon fiber gives PPS-CF exceptional properties including excellent resistance to solvents, corrosion, heat and flames. In addition, it offers superior strength, stiffness and dimensional stability, making it a specialized engineering plastic material to meet the demands of unique and challenging applications.
Exceptional resistance to high temperatures
The PPS-CF features a heat deflection temperature of up to 264 °C at 0.45 MPa and can operate continuously at temperatures above 200 °C. This significantly outperforms conventional PA-CF materials, which have maximum temperatures around 190 °C and 120 °C. Its exceptional heat resistance provides excellent creep resistance, making PPS-CF ideal for demanding industrial environments and applications.
| Filament type | PLA Basic | ABS | PC | Standard PA-CF | PA6-CF | PET-CF | PPA-CF | PPS-CF |
|---|---|---|---|---|---|---|---|---|
| Temperature of thermal deviation / °C (0,45 MPa) | 57 °C | 87 °C | 117 °C | 184 °C | 186 °C | 205 °C | 227 °C | 264 °C |
Superior fire resistance
PPS-CF achieves a UL-94 V-0 fire 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.
Unrivalled mechanical properties
Combining the stiffness of PPS polymers with the reinforcing power of carbon fibers, PPS-CF offers exceptional stiffness, flexural strength and tensile strength. Its superior dimensional stability and warpage resistance ensure that large-size printed products retain their precision and do not warp during the printing process, making it ideal for applications requiring high precision.
| Parameter | PET-CF | PPS-CF | Improvement % |
|---|---|---|---|
| Stiffness (flexural modulus – XY, dry state) | 5320 MPa | 7160 MPa | 34.59% |
| Strength (flexural strength – XY, dry state) | 131 MPa | 142 MPa | 8.40% |
Resistance to solvents and chemicals
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.
Extremely low water absorption
With an extremely low water absorption rate of just 0.05%, PPS-CF ensures that its mechanical and thermal properties remain stable even under wet conditions. Unlike ordinary PA-CF, which can soften and degrade when exposed to moisture, PPS-CF retains its strength and durability, making it the preferred choice for applications requiring high moisture resistance.

Bambu PPS-CF printing instructions:
- Nozzle temperature: the recommended range is 310 to 340 °C.
- Chamber temperature: the recommended range is 60 to 90 °C.
- Tip: Using higher values in these ranges can improve the mechanical properties of printed parts, especially in the Z-direction.
Drying recommendations:
- Drying temperature:
In oven: 100°C to 140°C for 8 to 12 hours.
On the heating platform of the X1 printer: 110°C to 120°C in 10 to 12 hours (less efficient than a drying oven).
- Important note: Higher temperatures in the drying range give better results, but do not exceed 160 °C to avoid damaging the reel.

Storage tips:
- Storage conditions: To prevent moisture absorption from the filament, use an airtight container with desiccant during printing.
