PA (Nylon) vs ASA

Compare PA (Nylon) and ASA filaments side-by-side so you can pick the right one for your 3D printing project.

PA (Nylon) vs ASA: PA (Nylon) is known for general use, while ASA is known for excellent uv resistance (outdoors indefinitely). PA (Nylon) is easier to print; PA (Nylon) prints at higher nozzle temperatures (240-285°C vs 220-275°C). Choose PA (Nylon) for general use, or ASA for excellent uv resistance (outdoors indefinitely).

Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.

Strengths Comparison

PA (Nylon) Strengths

    ASA Strengths

    • Excellent UV resistance (outdoors indefinitely), tough, matte surface
    • Less warping than ABS; low viscosity enables very high speed printing
    • High heat tolerance (~boiling water range)

    Considerations

    PA (Nylon) Caveats

      ASA Caveats

      • Still off-gasses; enclosure/ventilation recommended
      • Can still warp; needs tuning

      Frequently Asked Questions

      What is the difference between PA (Nylon) and ASA?
      PA (Nylon) prints at 240-285°C nozzle / 70-115°C bed (No enclosure, low moisture sensitivity). ASA prints at 220-275°C nozzle / 90-110°C bed (Recommended enclosure, moderate moisture sensitivity).
      Is PA (Nylon) or ASA stronger?
      Our dataset does not include comparable tensile strength values for both. Qualitatively, PA (Nylon) is suited to , while ASA is suited to excellent uv resistance (outdoors indefinitely).
      Which prints at a higher temperature, PA (Nylon) or ASA?
      PA (Nylon) prints at a higher temperature (240-285°C nozzle vs 220-275°C for ASA).
      Is PA (Nylon) or ASA better for beginners?
      PA (Nylon) is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
      Should I use PA (Nylon) or ASA for outdoor use?
      For outdoor use, ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose PA (Nylon) instead when .
