Prusament TPU 95A vs ASA

Compare Prusament TPU 95A and ASA filaments side-by-side so you can pick the right one for your 3D printing project.

Prusament TPU 95A vs ASA: Prusament TPU 95A is known for excellent layer adhesion, while ASA is known for excellent uv resistance (outdoors indefinitely). Prusament TPU 95A is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 235°C). Choose Prusament TPU 95A for excellent layer adhesion, 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

Prusament TPU 95A Strengths

  • Excellent layer adhesion; extremely impact resistant; highly durable
  • Great for combat robots, tactical/rough-use parts
  • Rubber-like parts (gaskets, grips, bumpers, wheels)

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

Prusament TPU 95A Caveats

  • Slow printing; retraction can cause jams (especially in Bowden setups)
  • Stringing is common
  • Very moisture sensitive; wet TPU prints poorly

ASA Caveats

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

Frequently Asked Questions

What is the difference between Prusament TPU 95A and ASA?
Prusament TPU 95A prints at 235°C nozzle / 65°C bed (No enclosure, low moisture sensitivity). ASA prints at 220-275°C nozzle / 90-110°C bed (Recommended enclosure, moderate moisture sensitivity).
Is Prusament TPU 95A or ASA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Prusament TPU 95A is suited to excellent layer adhesion, while ASA is suited to excellent uv resistance (outdoors indefinitely).
Which prints at a higher temperature, Prusament TPU 95A or ASA?
ASA prints at a higher temperature (220-275°C nozzle vs 235°C for Prusament TPU 95A).
Is Prusament TPU 95A or ASA better for beginners?
Prusament TPU 95A is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
Should I use Prusament TPU 95A or ASA for flexible parts?
For flexible parts, Prusament TPU 95A is usually the better fit (Excellent layer adhesion). Choose ASA instead when excellent uv resistance (outdoors indefinitely).
