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 extraordinary properties, including excellent resistance to solvents, corrosion, heat, and flames. In addition, the material offers superior strength, stiffness, and dimensional stability, making it a specialized engineering plastic that meets the requirements of unique and demanding applications.
Extremely high heat resistance
PPS-CF has a heat deflection temperature of up to 264°C at 0.45 MPa and can continuously operate at temperatures above 200°C. This significantly surpasses normal PA-CF materials, which have maximum temperatures around 190°C and 120°C. The excellent heat resistance also ensures outstanding creep resistance, making PPS-CF ideal for demanding industrial environments and applications.
| Filament Type | PLA Basic | ABS | PC | Normal PA-CF | PA6-CF | PET-CF | PPA-CF | PPS-CF |
|---|---|---|---|---|---|---|---|---|
| Heat Deflection Temperature / ℃ (0.45 MPa) | 57 ℃ | 87 ℃ | 117 ℃ | 184 ℃ | 186 ℃ | 205 ℃ | 227 ℃ | 264 ℃ |
Excellent flame retardant properties
PPS-CF achieves a UL-94 V-0 flame retardant rating, providing superior safety and reliability in critical areas such as electronics and automotive components. PPS-CF ensures long-term durability and peace of mind, even under the most demanding conditions.
Unmatched mechanical properties
The combination of the stiffness of the PPS polymer and the reinforcing effect of carbon fiber gives PPS-CF extraordinary stiffness, flexural strength, and tensile strength. Its excellent dimensional stability and resistance to shrinkage ensure that large prints maintain precision and avoid deformation during the printing process, making the material perfect for high-precision applications.
| Property | 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 excellent resistance to solvents and chemicals, surpassed only by PTFE (Teflon). The material is virtually insoluble in all solvents below 200 °C and shows exceptional resistance to acids, bases, and salts under normal conditions. This makes PPS-CF the ideal choice for demanding environments where chemical stability is crucial.
Extremely low water absorption
With a very low moisture absorption of only 0.05%, PPS-CF maintains its mechanical and thermal properties even under humid conditions. Unlike common PA-CF, which can soften and degrade with moisture, PPS-CF retains its strength and durability, making it the best choice for applications requiring high moisture resistance.

Print Tips for Bambu PPS-CF
Recommended Print Settings:
-
Nozzle Temperature: 310 – 340 °C
-
Chamber Temperature: 60 – 90 °C
-
Tip: Using higher temperatures within these ranges can improve the mechanical properties of the printed parts, especially in the Z-direction.
Drying:
-
Drying in a blast drying oven: 100 – 140 °C for 8 – 12 hours
-
Drying on the X1 printer's heatbed: 110 – 120 °C for 10 – 12 hours (less effective than blast drying oven)
-
Important: Higher temperatures within the drying range yield better results, but do not exceed 160 °C to avoid damaging the spool.
-
Further Information: See “Printing tips for Engineering materials” on WIKI for more details.
Storage:
-
Storage Conditions: To prevent the filament from absorbing moisture, store it in an airtight container with desiccant during printing.
-
More Details: See “Printing tips for Engineering materials” on WIKI.
Annealing of Printed Parts:
-
If prints need post-processing by annealing, refer to the Technical Data Sheet (TDS) and the WIKI section Work After Printing Finished.
