Filatech TPU vs ASA

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

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

Filatech TPU 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

Filatech TPU 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 Filatech TPU and ASA?
Filatech TPU prints at 235°C nozzle / 50°C bed (No enclosure, low moisture sensitivity). ASA prints at 220-275°C nozzle / 90-110°C bed (Recommended enclosure, moderate moisture sensitivity).
Is Filatech TPU or ASA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Filatech TPU is suited to excellent layer adhesion, while ASA is suited to excellent uv resistance (outdoors indefinitely).
Which prints at a higher temperature, Filatech TPU or ASA?
ASA prints at a higher temperature (220-275°C nozzle vs 235°C for Filatech TPU).
Is Filatech TPU or ASA better for beginners?
Filatech TPU is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
Should I use Filatech TPU or ASA for flexible parts?
For flexible parts, Filatech TPU is usually the better fit (Excellent layer adhesion). Choose ASA instead when excellent uv resistance (outdoors indefinitely).
