Carbon Fiber PETG vs ASA

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

Carbon Fiber PETG vs ASA: Carbon Fiber PETG is known for greatly improved stability and support quality vs petg, while ASA is known for excellent uv resistance (outdoors indefinitely). Carbon Fiber PETG is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 230-260°C). Choose Carbon Fiber PETG for greatly improved stability and support quality vs petg, 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

Carbon Fiber PETG Strengths

  • Greatly improved stability and support quality vs PETG
  • Stiffer than PETG; looks great (glossy walls)

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

Carbon Fiber PETG Caveats

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

ASA Caveats

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

Frequently Asked Questions

What is the difference between Carbon Fiber PETG and ASA?
Carbon Fiber PETG prints at 230-260°C nozzle / 70-90°C bed (Optional enclosure, moderate moisture sensitivity). ASA prints at 220-275°C nozzle / 90-110°C bed (Recommended enclosure, moderate moisture sensitivity).
Is Carbon Fiber PETG or ASA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Carbon Fiber PETG is suited to greatly improved stability and support quality vs petg, while ASA is suited to excellent uv resistance (outdoors indefinitely).
Which prints at a higher temperature, Carbon Fiber PETG or ASA?
ASA prints at a higher temperature (220-275°C nozzle vs 230-260°C for Carbon Fiber PETG).
Is Carbon Fiber PETG or ASA better for beginners?
Carbon Fiber PETG is better for beginners: enclosure is optional and moisture sensitivity is moderate, vs recommended enclosure and moderate moisture for ASA.
Should I use Carbon Fiber PETG or ASA for outdoor use?
For outdoor use, ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose Carbon Fiber PETG instead when greatly improved stability and support quality vs petg.
