Bambu Pet Cf Black

Bambu Lab PET-CF Filament 

Bambu Lab PET-CF Filament is a blend of tough PET and carbon fiber. The carbon fiber enhances hardness and mechanical strength while maintaining the low warping and shrinkage typical of standard PET. Bambu Lab PET-CF has excellent high temperature resistance and a soft glow appearance. Its outstanding strength, heat resistance, dimensional stability, and low moisture absorption make Bambu Lab PET-CF Filament with reusable spool an ideal choice for load-bearing structures or prints used in high-temperature and humid environments.

High dimensional stability

Due to the creep and warping resistance of PET-CF, prints can achieve excellent matching accuracy.

Exceptional thermal resistance

How to Optimize Your Printing

Based on the properties of PET-CF, it’s strongly recommended to consider the following tips to realize best performance:

Sample Projects

1. Dry Your Filament

Due to high moisture absorption rate of PET-CF, it's strongly recommended to dry it to prevent poor layer adhesion and brittleness.
Drying Condition:
Blast Drying Oven: 80 °C, 8 - 12h
X1 Series Heatbed: 90 - 100 °C, 12h

2. Hardened Steel Nozzle

Carbon fiber filament may wear out the nozzle; use a hardened steel nozzle to avoid abrasion.

3. Seal with desiccant to prevent moisture and achieve ideal printing results.

4. Other Settings

Build Plate & Bed Temperature: Smooth PEI Plate (70-100 °C); Textured PEI Plate (70-100 °C)
