Stiffness (Flexural modulus - XY, dry state)	4870 MPa	5460 MPa	4230 MPa	9860 MPa
Strength (Bending strength - XY, dry condition)	141 MPa	151 MPa	125 MPa	208 MPa

Industrial precision

Achieve industrial precision with Bambu PPA-CF. Its superior dimensional stability ensures that your high-precision prototypes match your design drawings exactly, without warping or deformation. Trust PPA-CF for the accuracy you need in every project.

Stable performance in humid conditions

Bambu PPA-CF supports long-term, stable use in humid environments, even underwater. With a moisture absorption rate that is 66% lower than normal PA6-CF, it maintains its stiffness and thermal properties over time. Whether you are printing propeller blades, customizing surfboards, or other water-resistant applications, PPA-CF delivers reliable performance.

Unparalleled performance at high temperatures

Bambu PPA-CF has exceptional heat resistance and can withstand prolonged exposure to temperatures up to 227°C without compromising structural integrity or performance. This filament remains reliable and robust in extreme environments, making it perfect for industrial, mechanical or automotive parts that must withstand ultra-high temperatures.

Printing tips

Drying recommendations:

• Drying temperature:

  • In a blast drying oven: 100 °C to 140 °C for 8–12 hours.

  • On the X1 printer's heatbed: 110°C to 120°C for 10–12 hours (less effective than a blast drying oven).

• Important note: Higher temperatures within the drying range will give better results, but do not exceed 160°C to avoid damage to the coil.

• Additional information: For more details, see Printing tips for Engineering materials on WIKI.

Storage tips:

• Storage conditions: To prevent the filament from absorbing moisture, use an airtight storage container with desiccant during printing.

• For further details: See Printing tips for Engineering materials on WIKI.

Annealing of print:

• If you need to anneal the prints, please refer to the Technical Data Sheet (TDS) and the WIKI section Work After Printing Finished .

Interface layer:

• To prevent the filament from damaging the print surface and promote model adhesion, apply a thin layer of glue stick for best results.
