Ultrafuse PP vs ASA

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

Ultrafuse PP vs ASA: Ultrafuse PP is known for very tough, while ASA is known for excellent uv resistance (outdoors indefinitely). Ultrafuse PP is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 240°C). Choose Ultrafuse PP for very tough, 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 PP Strengths

  • Very tough, durable, all-weather, extremely lightweight
  • Industrial-relevant material properties

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 PP Caveats

  • Even harder to print than PP; peels/curls more aggressively

ASA Caveats

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

Frequently Asked Questions

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