QIDI PAHT-GF (PPA-GF) Filament
QIDI PAHT-GF is specially developed for FDM 3D printing process. The base material is high-temperature nylon, compounded with 15% glass fiber, and a mesh skeleton structure is formed inside. It has the characteristics of low moisture absorption, high strength, high wear resistance, excellent chemical resistance and high heat resistance. It has good dimensional stability during printing, no warping and shrinkage, exquisite matte surface, and more diverse colors.
Stable mechanical properties
The addition of glass fiber significantly improves the mechanical strength of the material and solves the problem of warping and shrinkage in PPA printing. It also provides more color options and is suitable for manufacturing high-load materials with color requirements.

Printing Tips
1.Nylon material is very easy to absorb moisture within the environment, and printing after absorbing moisture will result in oozing, extrusion 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 PAHT-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 oozing, bubbles extruded and rough printing surface. Please dry the filament in an oven at 80-100℃ for 4-6h to restore the printing quality of QIDI PAHT-GF.
3. It is recommended to use hardened steel and above grade nozzles, which can effectively improve the print quality. Besides, it is recommended that the thickness of the heating block is longer 12mm.
4. After the printing is completed, the QIDI PAHT-GF printed part can be annealed to further improve the strength of print part. Annealing conditions: leave printing part in an oven at 80-100℃ for 4 to 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.

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.
