Ultrafuse PAHT-CF15 vs ASA

Compare Ultrafuse PAHT-CF15 and ASA filaments side-by-side so you can pick the right one for your 3D printing project.

Ultrafuse PAHT-CF15 vs ASA: Ultrafuse PAHT-CF15 is known for massively stiffer/tougher/more heat & abrasion resistant than nylon, while ASA is known for excellent uv resistance (outdoors indefinitely). Ultrafuse PAHT-CF15 is easier to print; Ultrafuse PAHT-CF15 prints at higher nozzle temperatures (270°C vs 220-275°C). Choose Ultrafuse PAHT-CF15 for massively stiffer/tougher/more heat & abrasion resistant than nylon, 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 PAHT-CF15 Strengths

  • Massively stiffer/tougher/more heat & abrasion resistant than nylon
  • Warping reduced enough to be fairly easy to print (with correct setup)
  • Viable alternative to machined aluminum for some parts

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 PAHT-CF15 Caveats

  • Higher print temps; hardware wear if not equipped

ASA Caveats

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

Frequently Asked Questions

What is the difference between Ultrafuse PAHT-CF15 and ASA?
Ultrafuse PAHT-CF15 prints at 270°C nozzle / 100°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 PAHT-CF15 or ASA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Ultrafuse PAHT-CF15 is suited to massively stiffer/tougher/more heat & abrasion resistant than nylon, while ASA is suited to excellent uv resistance (outdoors indefinitely).
Which prints at a higher temperature, Ultrafuse PAHT-CF15 or ASA?
Ultrafuse PAHT-CF15 prints at a higher temperature (270°C nozzle vs 220-275°C for ASA).
Is Ultrafuse PAHT-CF15 or ASA better for beginners?
Ultrafuse PAHT-CF15 is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
Should I use Ultrafuse PAHT-CF15 or ASA for outdoor use?
For outdoor use, ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose Ultrafuse PAHT-CF15 instead when massively stiffer/tougher/more heat & abrasion resistant than nylon.
