eSUN PA12 Black Nylon Filament 1 kg
eSUN PA12 Black is a black 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.
Important: eSUN PA12 Black 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, but proper drying, dry box printing and a hotend that works stably at 260–290 ℃ are required for good results.
✅ Key advantages
- PA12 nylon: engineering nylon for strong and working parts.
- 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.
- Black technical color: practical shade for housings, mechanics, automotive and industrial parts.
- Not carbon fiber: the material does not require a mandatory hardened nozzle.
