Filazoo ASA-CF Filament – UV-Resistant Carbon Fiber, 1.75mm, 1kg

ASA-CF combines ASA polymer with carbon-fiber reinforcement: you keep ASA's weather and UV resistance while gaining rigidity, dimensional stability, and a matte technical finish. ABS-CF, ABS-GF, PETG-CF, and ASA-CF compared sets out what each of our filled materials is actually for.

Yes — this is what it's built for. ASA resists UV and weathering better than any other base material we stock, which makes ASA-CF a strong choice for outdoor housings, brackets, automotive accessories, and equipment parts that live in sunlight. PC vs. ABS vs. ASA vs. PETG compares the options on real UV and temperature terms.

Carbon fiber makes it more rigid and dimensionally stable than standard ASA, with a more refined matte surface and reduced shrinkage. The trade-off is real: added rigidity means less flexibility and lower impact tolerance than unfilled ASA. What is carbon-fiber and glass-fiber filament? explains that stiffness-versus-toughness trade properly.

Strongly recommended. ASA-based materials want a warm, stable, draft-free environment; an enclosure cuts the risk of warping, cracking, and layer separation, especially on large models. Warping 101 explains the shrinkage physics behind that.

Yes. Carbon fiber rapidly wears brass nozzles — the opening enlarges and your dimensional accuracy goes with it. Use hardened steel, ruby, or another wear-resistant nozzle. Brass vs. hardened steel covers how quickly that wear happens and how to spot it.

A 0.6mm hardened-steel nozzle gives the most reliable flow and the least clogging risk. A 0.4mm wear-resistant nozzle works too, with a properly calibrated material profile. Nozzle range is published on every spool — how to read a filament spec sheet explains what those numbers mean.

Recommended, especially after the spool has been open in humid air. Moisture causes popping, bubbles, rough surfaces, stringing, and inconsistent extrusion. Start at 80–90°C for roughly 6–8 hours. How to dry filament at home compares the equipment that can hold that temperature safely.

Start between 90°C and 110°C, with a suitable build surface and adhesive where needed. Large parts also benefit from a brim and a fully preheated enclosure. If the first layer still lifts, our bed adhesion troubleshooting guide works through the causes in order.

Stiffer and more dimensionally stable, yes. Whether that counts as "stronger" depends on the type and direction of load — carbon fiber improves rigidity but can reduce flexibility and some forms of impact resistance. What is carbon-fiber and glass-fiber filament? unpacks the difference between the two.

It suits many rigid functional parts, fixtures, brackets, and engineering prototypes. Real performance depends on geometry, print orientation, wall thickness, infill, layer adhesion, temperature, and applied load — and safety-critical parts need application-specific engineering evaluation. Weak layer bonding is the usual failure mode: see why parts split along layer lines.

Not necessarily. Carbon-fiber filaments are abrasive and relatively rigid, so use only feeders, nozzles, and automatic material systems approved for fiber-reinforced filament. An external spool holder is often the better option when the printer's automatic feed isn't rated for abrasives. See setting up Filazoo filament in your AMS and choosing the right nozzle.

ASA-based materials release noticeable odors and emissions when heated. Print in a well-ventilated area and follow your printer manufacturer's ventilation and filtration guidance. If you can't guarantee ventilation — a classroom or shared room, say — pick a lower-temperature material: our classroom filament guide covers the reasoning.

It handles more heat than PLA and most standard PETG. Actual service temperature depends on formulation, load, part design, print quality, and how long the heat lasts. PC vs. ABS vs. ASA vs. PETG compares the realistic options when heat is the deciding factor.
