Fillamentum ASA vs PETG

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

Fillamentum ASA vs PETG: Fillamentum ASA is known for excellent uv resistance (outdoors indefinitely), while PETG is known for tougher than pla. Fillamentum ASA is easier to print; Fillamentum ASA prints at higher nozzle temperatures (260°C vs 230-250°C). Choose Fillamentum ASA for excellent uv resistance (outdoors indefinitely), or PETG for tougher than pla.

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

Fillamentum 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)

PETG Strengths

  • Tougher than PLA, higher temp tolerance, more durable in real-world use
  • Good clarity and low friction among easy-to-print materials

Considerations

Fillamentum ASA Caveats

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

PETG Caveats

  • Overhangs/bridges sag; supports can be hard to remove
  • Absorbs water fairly quickly

Frequently Asked Questions

What is the difference between Fillamentum ASA and PETG?
Fillamentum ASA prints at 260°C nozzle / 110°C bed (No enclosure, low moisture sensitivity). PETG prints at 230-250°C nozzle / 70-90°C bed (Optional enclosure, moderate moisture sensitivity).
Is Fillamentum ASA or PETG stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Fillamentum ASA is suited to excellent uv resistance (outdoors indefinitely), while PETG is suited to tougher than pla.
Which prints at a higher temperature, Fillamentum ASA or PETG?
Fillamentum ASA prints at a higher temperature (260°C nozzle vs 230-250°C for PETG).
Is Fillamentum ASA or PETG better for beginners?
Fillamentum ASA is better for beginners: enclosure is no and moisture sensitivity is low, vs optional enclosure and moderate moisture for PETG.
Should I use Fillamentum ASA or PETG for outdoor use?
For outdoor use, Fillamentum ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose PETG instead when tougher than pla.
