Smooth High-speed Printing
QIDI PET-CF Filaments prints out models with great gloss and beautiful texture.
Smart Fiber Reinforced Technology
QIDI Smart Fiber Reinforcement Technology significantly improves the mechanical properties and heat resistance of the material and releases internal stresses through the fiber mesh structure during the printing process, resulting in good dimensional stability of the printed part without warping.
Low Creep
The molecular chain structure of PET is highly regular and has a rigid benzene ring structure, so that PET has better mechanical properties and less deformation under long-term load. Compared with PA and PC materials, PET has better creep-resistance.
High Mechanical Strength
PET filament carbon fiber has higher strength and rigidity, Better impact Resistance,and Wear Resistance than regular PETG material.Suitable for applications requiring torsional, tensile, and impact strength.
Low Moisture Absorption
QIDI PET-CF has the characteristics of low moisture absorption, and the moisture absorption of this carbon fiber reinforced PET is only 0.5%.Moisture has no effect on the mechanical properties and dimensional stability of QIDI PET-CF.
Vacuum Aluminum Foil Packaging
According to the test, the water vapor transmission rate of ordinary sealed packaging is 4.76%, while the water vapor transmission rate of vacuum aluminum foil packaging we use is only 0.014%. It can be seen that vacuum aluminum foil packaging is more water-resistant.

Printing Tips
1. Although the moisture absorption of PET material is very low, it is very sensitive to moisture. Printing after absorbing moisture will result in ozzing, extruding with bubbles and rough surface appearance, thus reducing print quality. It is recommended that put the filament into a dry box (humidity below 15%) immediately after opening the QIDI PET-CF vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.
2. After the printing, the printed part can be annealed to further improve the strength of QIDI PET-CF print part. Annealing conditions: place the printed part at 80-100°C for 4-8 hours and cool to room temperature naturally.

- What is PET-CF filament? - PET-CF filament is a special type of material used in 3D printing. It is made from PET plastic that has been strengthened with carbon fiber. This makes it strong and stable, meaning it can hold its shape well while printing.
- What can I print with PET-CF filament? - You can use PET-CF filament to print many different kinds of objects, especially those that need to be strong or have a complex shape. It's great for making tools, parts for machines, or artistic creations!
- How should I store PET-CF filament? - To keep PET-CF filament in good condition, store it in a dry place, ideally in its original vacuum-sealed bag. This helps prevent it from absorbing moisture, which can make it difficult to print with.
- What temperature do I need to print PET-CF? - When printing with PET-CF filament, you should set your printer's nozzle temperature between 280 to 320 degrees Celsius. The bed temperature should be around 80 degrees Celsius for best results.
- Do I need a special printer for PET-CF filament? - It's best to use a 3D printer with a hardened steel nozzle because PET-CF can wear out softer nozzles like brass. Also, using a printer with an enclosed chamber helps control the printing environment.
- Can I use a brass nozzle with PET-CF filament? - No, you should not use brass or copper-plated nozzles with PET-CF filament, especially if they are small. These materials can be damaged by the carbon fiber in the filament.
- Is PET-CF filament safe to use? - Yes, PET-CF filament is safe to use for 3D printing. However, ensure good ventilation in your workspace while printing, as it may create small amounts of fumes.
- What are the benefits of using PET-CF filament? - Using PET-CF filament has several advantages. It is strong and durable, resists high temperatures, and does not absorb much moisture, which can help your prints come out clean and sharp.
- How does PET-CF compare to other materials? - PET-CF is stronger and more resistant to heat than regular PETG. It is also less likely to deform over time compared to some other materials, making it ideal for long-lasting prints.
- Where can I buy PET-CF filament? - You can purchase PET-CF filament online through our website, where it is readily available in different weights.
