QIDI PAHT-CF(PPA-CF) 3D Printer Filament
QIDI PAHT-CF(PPA-CF) is specially developed for FDM 3D printing process, the substrate is made of QIDI UltraPA(PPA)，high-temperature nylon with low moisture absorption, high strength, high abrasion resistance, excellent chemical resistance and high heat resistance, good dimensional stability and no warping during the printing process.
Higher Strength
QIDI TECH PAHT-CF(PPA-CF) Filament's Flex modulus up to 6.9 Gpa. 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
Temperature and Humidity Resistance
QIDI TECH PAHT-CF(PPA-CF) Filament's have good tensile and flexural strength performance in both wet and dry environments.

Printing Tips
• PAHT material 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 PAHT-CF vacuum foil bag for printing. Please put the unused filament back into the original aluminum foil bag for sealed storage.
• After the printing, the printed part can be annealed to further improve the strength of QIDI PAHT-CF print part. Annealing conditions: place the printed part at 80-100°C for 4-6 hours and cool to room temperature naturally.

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.
Product Size
