Smart Fiber Reinforced Technology
Smart Fiber Reinforced Technology greatly improves the mechanical properties and heat resistance of the material, and releases the internal stress during the printing process through the fiber mesh structure, resulting in good dimensional stability of the printed part and no warpage.
LOW CREEP
Rigid benzene ring structure
Better mechanical properties
Less deformation under long-term load
Better creep-resistance
Say Goodbye to Warping
The molecular chain structure of PET is highly regular and has a rigid ring structure, which makes PET have good mechanical properties, small deformation under long-term load, and better creep resistance than PA and PC materials.
PET-GF Prints are Suitable for Special Environments
PET-GF further enhances the rigidity, hardness and wear resistance of the material by adding chopped glass fibers. At the same time, glass fibers can inhibit the warping behavior of PET during printing, so that PET-GF only needs 70-80℃ base plate heating when printing, and does not require cavity insulation, making it very easy to print. Its 3D printed parts are suitable for use environments that require high heat resistance and long-term stress, such as 3D printer hot end parts.

Printing Tips
Additional Suggestions
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-GF vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.
2. After the material is damp, there will be more printing ozzing, bubbles extruded and rough printing surface. Please dry the filament in an oven at 100-120℃ for 4-6h to restore the printing quality of QIDI PET-GF.
3. Hardened steel and above grade nozzles shall be selected, which can effectively improve the print quality. Besides, it is recommended that the thickness of the heating block should no less than 12mm.
4. After the printing, the printed part can be annealed to further improve the strength of QIDI PET-GF print part. Annealing conditions: place the printed part at 80-100℃ for 4-8 hours and cool to room temperature naturally.
5.The filament has a high content of short-cut glass fiber and has been factory-dried, which makes it more brittle and prone to breaking. This is a normal phenomenon.

- What is PET-GF Filament? - PET-GF Filament is a type of material used for 3D printing. It's made from PET, which is strong and resistant to heat and moisture. This filament is great for making strong objects that can handle stress and high temperatures.
- Why is it important to dry the filament before use? - It's crucial to dry PET-GF Filament before you start printing. If it absorbs moisture, it can lead to problems like bubbling or a rough surface. Keeping it dry helps create high-quality prints.
- Can I use any type of nozzle for printing with PET-GF? - No, not all nozzles work well with PET-GF. It's best to use hardened steel nozzles instead of brass or copper ones, as they are more durable and produce better prints.
- What temperatures should I use for printing? - When printing with PET-GF, set your nozzle temperature between 260°C and 320°C. The bed temperature should be around 80°C for good adhesion.
- How can I store PET-GF Filament? - To keep your PET-GF Filament in good condition, store it in a dry container with a desiccant to absorb moisture. When you are not using it, put it back in its original sealed bag.
- Is PET-GF Filament good for outdoor use? - Yes, PET-GF Filament is suitable for outdoor use. It can withstand various weather conditions, making it ideal for outdoor projects.
- Why does PET-GF have better properties than regular PET? - PET-GF has added glass fibers which boost its strength, rigidity, and resistance to wear and tear. This makes objects printed with it sturdier than those made with plain PET.
- What materials can I print with PET-GF? - PET-GF can be printed to create parts for hotend applications, tools, or other items that need to withstand heat and stress.
- How long does it take to dry the filament? - To dry PET-GF Filament, place it in an oven at 100°C to 120°C for about 4 to 6 hours. This helps restore its printing quality.
- What are the color options available for PET-GF Filament? - PET-GF Filament comes in various colors. Currently, you can find options like brown and red to suit your project needs.
