AzureFilm PAHT CF is the easiest to print polyamide (PA6) based formula containing carbon fibers that you will be able to find on the market, with ability to be printable on non-heated chamber machines. Material is tough, has excellent abrasion resistance, fatigue endurance, good chemical resistance, high strenght and rigidity. Beside having excellent tensile and impact strength material compound allows short continuous use up to 160°C (Lifetime max. 200h) . Material is fully compatible with soluble supports such as PVA, BVOH, PVOH and fully compatible with breakaway supports such as HIPS. Its water uptake takes about 4 times longer to reach the saturation point compared to unmodified PA6 and it has saturation point 5 times lower than conventional PA6 materials. Thickness of fibers inside it's ranging from 0.4mm-0.6mm thats why the nozzle diameter has to be > 0.6mm.

Fiber reinforced composites offer exceptional mechanical properties. In addition to typical composite driving factors such as fiber orientation, fiber volume and way of stacking, scientist have found out that printing parameters such as infill density, nozzle speed, layer thickness, nozzle type, infill pattern, built orientation, bed temperatures have shown to influence mechanical properties.

Used for:

• Extremely smooth surface finish allows printability of functional prototypes
• Since it has exceptional mechanical properties it can be used for various fixtures, tooling, composite moulds for various manufacturing processes or self use
• In general its light weight, is key advantage for weight reduction, without loosing performance-grade strenght
• Compared to PLA, ABS, PETG or even other Carbon reinforced materials it can withstand significantly higher temperatures. Service temperature is enhanced up to 160°C (Lifetime max. 200h)
• Continuous service temperature 120°C
• High stiffness of the fibers themselves allow 3D printed parts to maintain their shape under high stress

Significant advantages of AzureFilm PAHT CF filaments:

• Cost effective - since we are using chopped up carbon fibers there is significant reduction in production length, allowing us to make our material cost friendly for any customer
• Higher temperature resistance up to 160°C
• More dimensional stability - Chopped carbon fibers are extremely strong and not only give high strenght and stiffness but also help prevent shrinking as the part is in the cooling down faze

Requirements to work with PAHT CF filaments:

• Heated print bed
• Hardened nozzle - Due to its abrasive structure, filament will wear down standard brass nozzle over a short period of time. Abrasion resistant nozzle is requirement for this type of filament. Since those type of nozzles tend to be less conductive then standard nozzles, usually higher extruder temperatures are recommended
• Heated filament chamber (optional) - Having the filament all the time in dry place, with working temp. ready is an optional thing to ensure consistently controlled environment for best product quality
• Closed environment (optional) - Ensuring consistent controlled environment is very important factor that allows better end class quality of the product although this filament has ability to be 3D printed on non-heated chamber machines

Printing Recommendations:

• Nozzle temperature: 270 – 290°C
• Heated bed: recommended 90-120°C
• Print speed: 40 – 60 mm/s
• Layer height: 0,2 mm
• Nozzle dimension: 0,6 mm
• Build platform: Blue tape, Kapton tape, glass bed + Dimafix spray
