3DXTech CarbonX™ ASA+CF Carbon-Fiber Reinforced ASA — Stiff, Low-Warp, Weatherproof
Carbon-Fiber Reinforced ASA — Stiff, Low-Warp, Weatherproof
A high-performance filament that reinforces 3DXTech's premium ASA resin with 15% high-modulus carbon fiber. It keeps ASA's excellent UV and weather resistance while adding the stiffness, dimensional stability, and low-warp behavior that unfilled ASA can't match — ideal for structural, outdoor, and automotive parts.

The weather resistance of ASA — with the stiffness of carbon fiber.
ASA is already one of the best filaments for outdoor and automotive parts thanks to its UV and weather resistance. CarbonX ASA+CF takes that base resin and reinforces it with 15% high-modulus carbon fiber — not carbon powder or milled fiber — to deliver high stiffness, dimensional stability, and low-warp behavior. The result is a structural filament that stays flat, holds tolerance, and survives the elements, with a premium matte-black finish straight off the bed.
Stiffness and dimensional stability — without giving up weatherproofing.
Carbon fiber for rigidity; ASA for UV and weather resistance.
The carbon fiber roughly doubles stiffness versus unfilled ASA and lowers the coefficient of thermal expansion, so large flat parts warp less and stay dimensionally true. Because it inherits ASA's chemistry, it holds up outdoors where ABS would yellow and crack. That combination makes it a natural fit for load-bearing parts with tight tolerances.
Rigid, weather-stable, and easy to print.
CarbonX ASA+CF is built for structural, outdoor-rated applications — and unlike ultra-high-temp grades, it prints in the same easy temperature window as standard ASA. All values from the 3DXTech TDS Rev 1.0 (ISO test methods).
Roughly double the stiffness of unfilled ASA.
15% carbon fiber lifts the tensile modulus to 5,355 MPa while keeping ASA's easy print behavior.
The carbon reinforcement does the structural work: a 5,355 MPa tensile modulus and 5,210 MPa flexural modulus keep printed parts rigid under load, with 48 MPa tensile strength and 78 MPa flexural strength. Low ~3% elongation is typical of a stiff, fiber-filled composite, and a 105°C glass transition sits comfortably above PLA and PETG for outdoor, weather-exposed parts.
High stiffness (ISO 527) from 15% carbon fiber — roughly double unfilled ASA; parts hold their shape under load.
Rigid in bending (ISO 178) with 78 MPa flexural strength — structural, not floppy.
Break strength per ISO 527 at 3% elongation — a stiff, rigid engineering filament.
DSC glass-transition temperature — comfortably above PLA and PETG for ambient outdoor use.
Inherits ASA's outstanding resistance to sunlight, moisture, and temperature swings — parts don't yellow or embrittle.
Runs at 235–255°C on a standard high-temp hotend — no ultra-high-temp hardware required.
Prints like ASA — with one important nozzle rule.
These are 3DXTech's recommended starting conditions. Carbon fiber is abrasive, so a hardened nozzle is a must; an enclosure helps large parts stay flat.
The same range as standard ASA — no 400°C+ hotend needed.
A standard heated bed with a PEI or ASA-slurry surface gives reliable first-layer grip.
A heated or draft-shielded enclosure helps large flat parts avoid warp — not strictly required for small parts.
Use a hardened-steel or ruby nozzle — carbon fiber wears out brass fast. 0.6 mm+ preferred for CF-filled flow.
Run 0.25 mm or thicker layers for the best strength and consistent flow with the filled filament.
Dry the filament before a long print if it has been exposed to humidity, for the best surface and consistency.
Built for structural, outdoor-rated parts.
A printed hydrofoil fuselage, in one piece.
Stiff, light, weatherproof, and dimensionally true.
This foil-wing fuselage is a textbook ASA+CF part: a long, thin, aerodynamic geometry that must stay dimensionally true, survive water and UV exposure, and carry load without flexing. The internal vane structure prints cleanly thanks to the low-warp matrix, and the matte-black carbon-fiber surface needs no finishing.

FAQ
3DXTech CarbonX ASA+CF — Common Questions
What temperature does CarbonX ASA+CF print at?
It prints in the same easy range as standard ASA — roughly 235–255°C extruder and a 90–110°C bed. A heated or draft-shielded enclosure helps large parts stay flat, but it does not need a 400°C+ hotend the way high-temp polymers like PEEK do.
Why do I need a hardened nozzle?
The carbon fiber that gives this filament its stiffness is abrasive and will quickly wear out a standard brass nozzle. Use a hardened-steel or ruby nozzle, 0.4 mm minimum; a 0.6 mm or larger nozzle gives smoother flow and fewer clogs.
What diameters and reel sizes are available?
1.75 mm and 2.85 mm diameters, on 750 g reels ($67.50) and 2 kg reels ($155.00). The 2 kg reel is a special order with a 10-unit minimum — contact Rev1 to arrange it. The 750 g reel fits Bambu AMS, Creality CFS, and Anycubic ACE Pro systems.
Is it good for outdoor parts?
Yes — that's one of its strongest use cases. It inherits ASA's excellent UV and weather resistance, so parts hold their color and mechanical properties in sustained sun and moisture where ABS would yellow and crack, while the carbon fiber keeps large parts dimensionally stable.
How stiff is it compared to regular ASA?
The 15% carbon fiber roughly doubles stiffness: a 5,355 MPa tensile modulus and 5,210 MPa flexural modulus versus roughly 2,000 MPa for unfilled ASA. The trade-off is ductility — about 3% elongation at break — which is what structural parts want.
Is it ESD-safe or conductive?
No. Its surface resistance is greater than 10ⁿ Ohm/sq, so it's electrically insulative — a structural filament, not an ESD-safe grade. For ESD-safe parts, 3DXTech offers a dedicated 3DXSTAT ESD line; ask Rev1 for the right grade.
Matte carbon-fiber black — with a clean structural surface.
CarbonX ASA+CF ships in a single, purpose-built color: a deep matte carbon-fiber black. Carbon fiber is inherently black, so there are no other color options for this material — and the filled matrix gives printed parts a premium, low-gloss finish straight off the plate. It's available in 1.75 mm and 2.85 mm on 750 g and 2 kg reels; choose your diameter and reel in the buy-box, or ask us about the 2 kg special order and bulk pricing.
