Suited for

  • Structures under load in hot, humid environments
  • Supports near heat sources
  • Parts that need dimensional stability

Watch out for

  • More brittle on impact than the nylons
  • Does not resist acids and alkalis

Frequently asked questions

What people usually ask about PET-CF.

Still have a question? Message us on WhatsApp

How heat-resistant is PET-CF?
HDT is 205 °C at 0.45 MPa and 182 °C at 1.8 MPa (ISO 75), measured on specimens with 100 % infill, according to the official Bambu Lab data sheet. It is a reference value for comparing materials: the real part varies with orientation, infill and wall thickness.
Is PET-CF kept in stock?
No. It is an engineering material on request: we buy the lot for your order, and the minimum volume depends on the material and the size of the part. The lead time includes purchasing and drying the material, added to the normal production lead time of 24 h to 96 h.
How is PET-CF printed?
Only with a hardened nozzle: carbon and glass fibres wear down a brass nozzle. The process is nozzle at 260–290 °C, bed at 80–100 °C and chamber at 45–60 °C. The filament is oven-dried (80 °C · 8–12 h) before printing and stored below 20 % RH.
What are the limits of PET-CF?
More brittle on impact than the nylons. Does not resist acids and alkalis.
Are the PET-CF values guaranteed?
No. Real parts vary with orientation, infill, wall thickness and material condition, and the values are not guaranteed or certified. For critical applications (safety, structural load, food contact or medical use), validate the part in your application before series production.
