Printing Tips
1. Nylon material is very easy to absorb moisture within the environment, and printing after absorbing moisture will result 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 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 ozzing, 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.
