Ultrafuse ASA vs ASA

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

Ultrafuse ASA vs ASA: Ultrafuse ASA is known for excellent uv resistance (outdoors indefinitely), while ASA is known for excellent uv resistance (outdoors indefinitely). Ultrafuse ASA is easier to print; Ultrafuse ASA prints at higher nozzle temperatures (275°C vs 220-275°C). Choose Ultrafuse ASA for excellent uv resistance (outdoors indefinitely), 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

Ultrafuse 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)

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

Ultrafuse ASA Caveats

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

Frequently Asked Questions

What is the difference between Ultrafuse ASA and ASA?
Ultrafuse ASA prints at 275°C nozzle / 105°C bed (No enclosure, low moisture sensitivity). ASA prints at 220-275°C nozzle / 90-110°C bed (Recommended enclosure, moderate moisture sensitivity).
Is Ultrafuse ASA or ASA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Ultrafuse ASA is suited to excellent uv resistance (outdoors indefinitely), while ASA is suited to excellent uv resistance (outdoors indefinitely).
Which prints at a higher temperature, Ultrafuse ASA or ASA?
Ultrafuse ASA prints at a higher temperature (275°C nozzle vs 220-275°C for ASA).
Is Ultrafuse ASA or ASA better for beginners?
Ultrafuse ASA is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
Should I use Ultrafuse ASA or ASA for outdoor use?
For outdoor use, Ultrafuse ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose ASA instead when excellent uv resistance (outdoors indefinitely).
