Collection: ASA Carbon Fibre Filament

They are two different constructions, not one material under two names. ASA CF mixes chopped carbon fibre evenly through the ASA, which is the traditional approach to a CF composite. ASA-CFRP-CF is co-extruded: a carbon fibre reinforced core wrapped in an ASA outer layer, which gives a smoother surface than a standard blend while adding the same stiffness. Both need an enclosure and a hardened nozzle. Choose ASA-CFRP-CF when surface finish matters, and ASA CF if you want the conventional blend.

No. ASA's weather resistance comes from the polymer itself, not from a coating or additive that carbon fibre could dilute, so a CF grade keeps it. In the co-extruded ASA-CFRP-CF the surface facing the sun is ASA anyway, because the fibre sits in the core. This is the whole reason to reach for ASA CF instead of ABS CF on anything that lives outdoors.

Yes, noticeably. Both constructions add real rigidity and dimensional stability over standard ASA, with reduced shrinkage. The trade is a little flexibility: a CF grade resists bending where standard ASA would flex, which is what you want in a bracket and not what you want in a part that needs to give.

Yes, for both constructions, and it is not optional. Carbon fibre is abrasive and will wear a standard brass nozzle down quickly, whether the fibre is blended through the filament or concentrated in a core. Fit a hardened steel nozzle before printing either one.

Nozzle 250 to 270°C, bed 80 to 100°C, printed in an enclosure. Dry at 70 to 80°C for 4 to 6 hours if the spool has been open for a while. Note that it runs hotter than ABS CF at 240 to 260°C, so do not reuse a carbon fibre ABS profile unchanged.

ASA CF, whenever the part lives outdoors. The two are close on stiffness and the deciding factor is UV exposure: ASA holds its colour and surface finish where ABS yellows and chalks in sunlight. Keep ABS CF for indoor, under-bonnet and workshop parts, and use ASA CF for anything mounted outside.

Yes, and it is one of the better uses for it. Drone and RC components need to stay rigid in thin sections, and they usually live outdoors, which is exactly where carbon fibre reinforcement and ASA's UV stability pay off together. Arms, brackets, mounts and structural parts all suit it.
