Rev1 ASA-CF The UV-Stable, Weatherproof, Carbon-Reinforced Structural Filament
The UV-Stable, Weatherproof, Carbon-Reinforced Structural Filament
ASA-CF is carbon-fiber-reinforced ASA — the UV-stable, weatherproof engineering plastic that won’t yellow, fade, or crack in sunlight and weather, now stiffened with chopped carbon fiber for higher rigidity, better strength-to-weight, greater dimensional stability, and far less warping than plain ASA. It’s the go-to for outdoor structural and load-bearing parts. Carbon fiber is abrasive, so it prints best with a hardened-steel nozzle in an enclosed printer — in one premium Carbon Fiber matte-black finish, on 1 kg and 3 kg spools. Full specifications →

Carbon-reinforced, dimension-locked, supported by humans.
Rev1 ASA-CF is precision-extruded, carbon-fiber-reinforced 1.75 mm filament, wound evenly and vacuum-sealed with desiccant, then stocked and supported from Auburn Hills, Michigan.
When the part has to live outside — and stay stiff.
PLA yellows and softens in the sun; PETG holds up but flexes; plain ASA is weatherproof but can warp on big flat parts. ASA-CF is carbon-fiber-reinforced ASA that shrugs off sunlight, rain, and heat without fading, chalking, or cracking — while the chopped carbon fiber adds rigidity, strength-to-weight, and dimensional stability, so parts hold their shape with far less warping than plain ASA. The trade-off is that ASA-CF wants an enclosed, draft-free printer and a hardened-steel nozzle — give it that and Rev1 ASA-CF makes durable, weatherproof, structural parts in a premium Carbon Fiber matte-black finish.
Even diameter and a clean wind for reliable, warp-free runs.
Round, consistent 1.75 mm carbon-filled filament feeds smoothly so long enclosed prints don’t fail.
Every Rev1 ASA-CF spool is wound evenly and held to a tight diameter, so it feeds without under-extrusion across a full 1 kg or 3 kg run. Because carbon fiber is abrasive, run a hardened-steel nozzle. Vacuum-sealed with desiccant to arrive dry — so it prints clean straight out of the bag.
Won’t yellow, fade, chalk, or crack in sunlight and weather — the go-to for parts that live outside.
Holds its shape in hot cars, enclosures, and near motors — far past where PLA and PETG soften.
Chopped carbon fiber adds rigidity, strength-to-weight, and dimensional stability — much lower warp than plain ASA.
One premium matte-black carbon finish. In-stock 1 kg ships fast from Michigan; 3 kg is made-to-order in 1–3 weeks.
Print settings for clean, crack-free ASA-CF.
ASA-CF prints like ASA and rewards a stable, draft-free environment. An enclosure, a hot bed, and minimal part cooling keep corners down and layers bonded — and because the carbon fiber is abrasive, a hardened-steel nozzle is required.
Hotter than PETG for strong layer adhesion; carbon fiber is abrasive, so a hardened-steel nozzle is required.
A hot bed plus glue or an adhesive sheet prevents the corners from lifting.
An enclosure holds chamber heat and blocks drafts — the #1 fix for warping and cracking.
ASA-CF emits a mild styrene odor while printing — lower than ABS, but still run it in a ventilated space or with filtration.
Recommended slicer settings
A solid starting profile for Rev1 ASA-CF on an enclosed FDM printer with a hardened-steel nozzle. Tune cooling and chamber temperature for your machine.
| Setting | Recommended | Notes |
|---|---|---|
| Nozzle temperature | 240–260 °C | Run hot for strong layer bonding and to reduce cracking. |
| Bed temperature | 90–110 °C | Glue stick or ASA slurry on glass/PEI for a strong first layer. |
| Chamber / enclosure | Warm, draft-free | The single biggest factor in warp- and crack-free ASA-CF. |
| Print speed | 30–60 mm/s | Moderate speeds help interlayer strength. |
| Part cooling fan | 0–20 % | Keep cooling low — too much fan cracks layers. |
| Retraction | 1–5 mm | Direct drive: ~1–2 mm. Tune to control stringing. |
| Nozzle type | Hardened steel, 0.4 mm + | Required — carbon fiber wears out brass; larger nozzles add strength. |
| Drying | 65–80 °C · 4–6 h | Only if exposed to humidity; ASA-CF is less hygroscopic than PETG. |
| Post-processing | Sand / seal | Carbon fiber gives a matte finish; light sanding evens the surface. Acetone vapor has limited effect with CF. |
Structural parts that have to survive sun, rain, and load.
The go-to material for structural parts that live outside.
ASA-CF trades PLA's easy printing for real outdoor structural performance: UV stability, weatherproofing, high heat resistance, and carbon-fiber stiffness, strength-to-weight, and dimensional stability with much lower warp than plain ASA. Stocked in a premium Carbon Fiber matte-black finish, 1 kg and 3 kg spools.
Sun, weather, and load? That's ASA-CF's home turf.
UV-stable and carbon-stiffened for exterior brackets that won't fade, flex, or crack in the sun.
Exterior mounting brackets, trim supports, and structural body fixtures that bake in the sun and get rained on — ASA-CF holds its color and its shape where ABS would yellow and plain ASA would warp, and the carbon fiber adds the rigidity load-bearing brackets need.
Weatherproof enclosures that shrug off sun and rain.
Rigid, UV-stable, carbon-reinforced boxes and cases for outdoor electronics and equipment.
ASA-CF is the outdoor enclosure material — carbon-stiffened walls that stay flat, clean snap-fits, and the weather resistance to sit outside for years without chalking, cracking, or fading.
Outdoor mounting brackets that stay stiff and true.
Dimensionally stable, carbon-reinforced fixtures that stand up to sun, heat, and the elements.
Print the outdoor-equipment mounts and brackets your install needs — ASA-CF keeps its shape through heat cycles and UV exposure, and the carbon fiber adds the stiffness and dimensional stability that plain ASA can't match.
Security-camera and sensor housings built for the weather.
Sealed, UV-stable, rigid shells that protect electronics outdoors year-round.
Outdoor camera and sensor housings live in full sun and driving rain — ASA-CF's weatherproofing keeps them from yellowing or cracking, and carbon-fiber rigidity keeps thin housing walls from flexing or warping around the optics.
Rooftop and solar mounts that stay rigid in the sun.
Load-bearing, UV-stable brackets that don't sag or warp under heat.
ASA-CF is the pick for rooftop and solar-panel mounting brackets — it stays UV-stable and weatherproof outdoors, while carbon-fiber stiffness and dimensional stability let it carry load through heat cycles where plain ASA would soften or creep.
Drone and UAV frames with real strength-to-weight.
Light, stiff, and impact-tough for airframes that fly in real weather.
Quadcopter and UAV frames need to be light and rigid at once — carbon fiber gives ASA-CF a high strength-to-weight ratio and low warp, while ASA's UV resistance and weatherproofing let the airframe live outdoors. Ask us about 3 kg spools and case pricing.
ASA-CF vs. plain ASA vs. PA12-CF.
Pick by where the part has to live. ASA-CF wins for outdoor structural parts — it keeps ASA's UV and weather resistance while adding carbon-fiber stiffness and dimensional stability; plain ASA is the value outdoor pick without the stiffness; PA12-CF is the tougher indoor engineering choice but isn't UV-stable.
| Rev1 ASA-CF | Plain ASA | PA12-CF | |
|---|---|---|---|
| UV / weather resistance | Excellent — won’t yellow | Excellent — won’t yellow | Poor (not UV-stable) |
| Stiffness / modulus | High — carbon-reinforced | Medium | High — carbon-reinforced |
| Dimensional stability / warp | Excellent — low warp | Fair (can warp) | Good |
| Heat resistance | High (~100 °C) | High (~100 °C) | High (~110 °C+) |
| Nozzle | Hardened steel required | Brass OK | Hardened steel required |
| Best for | Outdoor structural / load-bearing parts | Value outdoor / UV parts | Indoor engineering / tough functional parts |
General material guidance; exact performance depends on part geometry, print settings, and grade. ASA-CF is abrasive (hardened-steel nozzle) and carries a premium over plain ASA. For maximum outdoor UV without carbon fiber, choose plain ASA; for indoor stiffness, PA12-CF or PC+-CF; for easy prints, PLA or PETG.
Rev1 ASA-CF Technical Data
Mechanical & thermal properties
Typical ASA-CF reference values for engineering guidance — carbon fiber raises stiffness and strength and lowers elongation versus plain ASA. Printed-part performance varies with wall count, infill, layer height, and orientation — treat these as material-level guidance, not a part spec.

FAQ
Rev1 ASA-CF — Common Questions
Do I need a hardened nozzle to print ASA-CF?
Yes — required. The chopped carbon fiber that stiffens ASA-CF is abrasive and quickly wears out a standard brass nozzle. Run a hardened-steel (or ruby/tungsten) nozzle, 0.4 mm or larger. Otherwise ASA-CF prints like ASA: an enclosure and a hot bed are strongly recommended.
Is ASA-CF really UV-stable and weatherproof?
Yes — it keeps ASA’s signature advantage. ASA-CF resists UV and weather, so parts won’t yellow, fade, chalk, or crack in sunlight and rain the way ABS or PLA do — while the carbon fiber adds stiffness and dimensional stability. It’s the go-to for outdoor structural parts: automotive exterior brackets, weatherproof enclosures, camera housings, solar mounts, and drone frames.
What color and sizes are available?
One premium finish: Carbon Fiber matte black. It ships on 1 kg and 3 kg spools — 1 kg is in stock and ships fast from Michigan; 3 kg is made-to-order in 1–3 weeks. Pick your spool size in the buy-box, or ask us about case quantities.
How does ASA-CF compare to plain ASA?
ASA-CF keeps everything that makes ASA great outdoors — UV stability and weatherproofing — and the carbon fiber adds stiffness, better strength-to-weight, greater dimensional stability, and much lower warping. The trade-offs: it needs a hardened nozzle, only comes in matte-black carbon, and costs a premium over plain ASA. For maximum UV parts without carbon fiber, plain ASA is the value pick.
How do I stop ASA-CF from warping and cracking?
Carbon fiber already lowers warp versus plain ASA, but the basics still apply: enclose the printer, run a 90–110 °C bed with glue, keep part cooling low or off, and avoid drafts and AC vents. Keep the filament dry — a warm chamber and brims help large flat parts stay stuck.
What finish does ASA-CF have?
A premium matte carbon-black surface — the carbon fiber gives it a low-gloss, engineered look straight off the printer. Unlike plain ASA, acetone vapor-smoothing has limited effect with carbon fill; light sanding evens the surface if you want it smoother.
How heat-resistant is ASA-CF?
ASA-CF holds its shape to roughly 100 °C (glass transition ~100 °C, HDT ~100 °C), well past PLA and PETG — suitable for hot car exteriors, outdoor enclosures, and near-motor parts. For even higher sustained heat, step up to PC or PA (nylon).
When should I use plain ASA, PA12-CF, or PLA instead?
For maximum outdoor UV parts without the carbon-fiber cost or the abrasive nozzle, plain ASA is the value pick. For indoor stiffness and toughness, PA12-CF or PC+-CF are stronger (but not UV-stable). For easy, everyday prints, PLA or PETG are simpler and don’t need an enclosure or hardened nozzle. Choose ASA-CF when a part must be both weatherproof and stiff.
