eSUN PA12 White Nylon Filament 1 kg

eSUN PA12 White is a white engineering nylon filament based on PA12 for FDM/FFF 3D printing of strong, impact-resistant, wear-resistant and functional parts.

PA12 has low moisture absorption compared with many other nylon materials. This means printed parts are less affected by humidity and temperature, maintain geometry better and are suitable for mechanical components, housings, gears, brackets, automotive parts, electronics and industrial prototypes.

The white color is useful for technical prototypes, light-colored housings, demonstration models, functional equipment parts and products where a neutral clean appearance is required. Important: eSUN PA12 White is standard PA12 nylon without carbon fiber. It is not PA12+CF and not PA-CF. The material is not an abrasive carbon fiber filament, so a wear-resistant nozzle is not mandatory.

✅ Key advantages

• PA12 nylon: engineering nylon for strong, tough and working parts.
• White technical color: suitable for prototypes, housings, light-colored parts and demonstration models.
• Low moisture absorption: parts are less affected by ambient humidity and temperature.
• High toughness: the material withstands deformation better than brittle plastics.
• Elongation at break up to 165.41%: PA12 is suitable for tough functional parts.
• Impact resistance: suitable for parts exposed to mechanical impact.
• Wear resistance: useful for gears, guides, clips, mounts and sliding elements.
• Self-lubricating nylon behavior: important for mechanical parts and friction assemblies.
• Heat resistance: heat deflection temperature is 100 ℃ at 0.45 MPa.
• Not carbon fiber: the material does not require a mandatory hardened nozzle.

🔧 Printing recommendations

• Dry the spool at 70 ℃ for more than 12 hours before printing.
• During printing, use a dry box, eBOX or sealed filament container.
• Do not leave PA12 open in a humid room: the material can absorb moisture.
• Use a high-temperature hotend that works stably in the 260–290 ℃ range.
• A standard brass nozzle is suitable because PA12 White does not contain carbon fiber.
• Cooling is usually disabled to improve layer adhesion.
• For functional parts, start at 40–60 mm/s and increase speed after profile tuning.
• For large models, maintain stable temperature around the part and avoid drafts.
• For better bed adhesion, use a brim or a suitable adhesive layer.
• For gears, clips and mechanical assemblies, test clearances on the actual printer and profile.

🧩 Best applications

• ⚙️ Gears, toothed wheels and mechanical elements.
• 🔩 Brackets, mounts, holders, fixtures and clips.
• 🏭 Industrial jigs, fixtures and functional prototypes.
• 🚗 Automotive parts, technical inserts and mounting elements.
• ✈️ Aerospace prototypes and lightweight functional components.
• 🔌 Electrical and electronic housings, panels and protective elements.
• 🧩 Parts for equipment, machines, mechanisms and 3D printers.
• 🧪 Durable parts — strong working parts for testing and real use.
• ⚪ Light-colored technical models, demonstration prototypes and white housings.

✅ 3D printer compatibility

eSUN PA12 White is compatible with FDM/FFF 3D printers using 1.75 mm filament, supporting a 260–290 ℃ nozzle temperature range and a 70–90 ℃ heated bed. Stable printing requires dry material, a high-temperature hotend 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 the required hotend temperature and stable feeding of nylon filament.

📦 Storage and drying

• Dry PA12 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 bubbles, popping, roughness or weak layer adhesion appear, dry the material again.

❓ FAQ

 

 

Are PA12 and ePA12 the same material?

Yes. PA12 is the main commercial name, while ePA12 appears in eSUN technical documents and materials.

Does PA12 White contain carbon fiber?

No. eSUN PA12 White is standard PA12 nylon without carbon fiber. If PA12 with reinforcement is needed, choose the separate PA12+CF / ePA12-CF line.

Does PA12 need drying before printing?

Yes. PA12 should be dried at 70 ℃ for more than 12 hours. During printing, a dry box or eBOX is recommended.

Does PA12 White require a wear-resistant nozzle?

Standard PA12 does not contain carbon fiber and is not a highly abrasive material, so a hardened nozzle is not mandatory. The hotend must work stably at 260–290 ℃.

Is PA12 White suitable for gears?

Yes. PA12 is suitable for gears and mechanical parts thanks to wear resistance, self-lubricating nylon behavior, toughness and good fatigue resistance.
