eSUN PA12+CF Black Carbon Fiber PA12 Nylon Filament 1 kg

eSUN PA12+CF Black is a black engineering PA12 nylon filament reinforced with carbon fiber for FDM/FFF 3D printing of strong, stable, wear-resistant and functional parts.

PA12+CF offers low moisture absorption, high dimensional stability, chemical resistance, impact resistance, wear resistance and a matte carbon-fiber surface. Unlike standard nylon materials, the PA12 base is less affected by humidity and temperature, so printed parts maintain geometry better during use.

The black color makes the material universal for robots, drones, automotive components, electronic housings, gears, brackets, industrial fixtures, precision mechanical parts, aerospace prototypes and functional engineering products.

🔧 Printing recommendations

• Dry the filament at 70 ℃ for more than 12 hours before printing, especially after opening the spool.
• During printing, use a dry box, eBOX or sealed filament container.
• After fresh vacuum unpacking, the material may print more consistently, but drying is still recommended for reliable results.
• Use a hardened steel, ruby, tungsten carbide or another wear-resistant nozzle.
• Do not use a standard brass nozzle for regular printing: reinforcing fibers quickly wear brass.
• For long print jobs, a 0.6 mm or larger nozzle is preferable to reduce clogging risk.
• If possible, use hardened steel extruder gears.
• Keep the filament path as straight as possible: PA12+CF is rigid and does not tolerate sharp bends well.
• For strong parts, start at 40–80 mm/s and increase speed after profile tuning.
• For large parts, use an enclosure or stable temperature around the model.
• Use a brim or skirt to improve bed adhesion.
• If Z-hop leaves marks on the surface, disable Z-axis lift / Z-hop and optimize travel moves.

🧩 Best applications

• 🤖 Robots, robotic housings and mounts.
• 🚁 Drones, UAV components and lightweight rigid parts.
• 🚗 Automotive elements, mounts and functional prototypes.
• ✈️ Aerospace prototypes and technical components.
• ⚙️ Gears, toothed wheels and mechanical elements.
• 🏭 Industrial jigs, fixtures and tool fixtures.
• 🔌 Electrical and electronic housings, panels, holders and protective elements.
• 🧪 Precision engineering prototypes requiring dimensional stability.
• 🧵 Textile mechanism parts and pump elements.
• ⚫ Black matte technical parts with carbon-fiber texture.

✅ 3D printer compatibility

eSUN PA12+CF Black is compatible with FDM/FFF 3D printers using 1.75 mm filament, supporting a 250–290 ℃ nozzle temperature range and a 60–100 ℃ heated bed. Stable printing requires a high-temperature hotend, dry filament, a wear-resistant nozzle and a properly tuned profile.

The material can be printed on Bambu Lab, Creality, Prusa, Anycubic, QIDI, Flashforge, Raise3D, Voron and other FDM/FFF printers if the printer supports high-temperature printing, stable feeding of rigid composite filament and work with abrasive materials.

For hotends with PTFE tubing, check the maximum allowed temperature. For long PA12+CF printing, an all-metal hotend is recommended. It is also important to avoid sharp bends in the feeding path because the material is rigid and not as flexible as standard nylon or TPU.

PA12+CF vs PA-CF vs PET-CF vs PETG-CF

Material	Base	Main feature	When to choose
PA12+CF	PA12 nylon	Low moisture absorption, high dimensional stability, chemical resistance, carbon fiber reinforcement	For precision engineering parts, robots, drones, automotive components, electronics and humidity-sensitive parts
PA-CF	PA / nylon	High strength, toughness, wear resistance, suitability for mechanics and gears	For loaded mechanical parts, gears, mounts, industrial and automotive assemblies
PET-CF	PET	High rigidity, stability, heat resistance, low moisture absorption	For rigid heat-resistant housings, tool fixtures and industrial fixtures
PETG-CF	PETG	Easier printing, lower temperature profile, matte carbon-fiber surface	For technical housings, brackets and functional prototypes without extreme loads

Why a wear-resistant nozzle is needed

PA12+CF contains carbon fiber, and according to MSDS it also contains glass fiber. Therefore, the material is abrasive and quickly wears standard brass nozzles. When the nozzle wears, dimensional accuracy becomes worse, line width changes, extrusion becomes unstable and surface quality decreases.

For PA12+CF, hardened steel, ruby, tungsten carbide or another wear-resistant nozzle is recommended. A 0.4 mm nozzle can be used for small parts, but for long print jobs, stable feeding and reduced clogging risk, 0.6 mm is often better.

📦 Storage and drying

• Dry PA12+CF at 70 ℃ for more than 12 hours before printing.
• Use a dry box or eBOX during printing.
• After printing, return the spool to a sealed bag or container immediately.
• Store the material with silica gel or another desiccant.
• Do not leave the spool open in a humid room.
• If surface quality decreases, bubbles, popping or unstable extrusion appear, dry the material again.

🛡️ Safety during printing and post-processing

eSUN PA12+CF Black is not classified as a hazardous chemical under GHS, but standard safety measures should be followed during printing and post-processing. Print in a ventilated area and avoid overheating, open flames, sparks and hot surfaces.

When sanding, drilling, cutting or mechanically processing PA12+CF parts, safety glasses, a mask or respirator are recommended. Dust from carbon-fiber and glass-fiber-filled materials should not be inhaled, so post-processing should be performed carefully, with ventilation and proper cleaning of the work area.

❓ FAQ

 

 

 

Are PA12+CF, PA12-CF and ePA12-CF the same material?

Yes. eSUN content uses different names for the same product line.

How is PA12+CF Black different from PA-CF?

PA12+CF is based on PA12 and offers lower moisture absorption and higher dimensional stability. PA-CF is more focused on classic reinforced nylon properties: strength, toughness, wear resistance and mechanical parts.

Does PA12+CF need drying before printing?

Yes. Even with low moisture absorption, the material should be dried at 70 ℃ for more than 12 hours, especially after opening the spool or if print quality decreases.

Can PA12+CF be printed with a brass nozzle?

It is not recommended for regular printing. The material contains reinforcing fibers and wears brass quickly. Hardened steel, ruby, tungsten carbide or another wear-resistant nozzle is recommended.

Does PA12+CF require an enclosure?

An enclosure is not always mandatory, but it is recommended for large and functional parts. Stable temperature helps improve strength, reduce internal stress and achieve more repeatable results.

Is PA12+CF suitable for drones?

Yes. PA12+CF is suitable for drone and UAV components because of low moisture absorption, dimensional stability, impact resistance, rigidity and relatively low density.

Is PA12+CF suitable for gears?

Yes, the material is suitable for gears and mechanical elements thanks to the PA12 base, wear resistance and carbon fiber reinforcement. For accurate gear operation, clearances, print orientation and post-processing should be tested.

Is PA12+CF beginner-friendly?

PA12+CF is more demanding than PLA, PETG and standard decorative materials. Successful printing requires profile tuning experience, a dry box, high-temperature hotend, wear-resistant nozzle and proper material storage.
