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 PC Space Grade Strengths

  • Extremely stiff; useful where flex must be minimal
  • Surprisingly affordable in some brands

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 PC Space Grade Caveats

  • Feeding can be difficult unless spool is close/direct-fed

ASA Caveats

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

Frequently Asked Questions

What is the difference between Prusament PC Space Grade and ASA?
Prusament PC Space Grade prints at 290°C nozzle / 120°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 PC Space Grade or ASA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Prusament PC Space Grade is suited to extremely stiff, while ASA is suited to excellent uv resistance (outdoors indefinitely).
Which prints at a higher temperature, Prusament PC Space Grade or ASA?
Prusament PC Space Grade prints at a higher temperature (290°C nozzle vs 220-275°C for ASA).
Is Prusament PC Space Grade or ASA better for beginners?
Prusament PC Space Grade is better for beginners: enclosure is no and moisture sensitivity is low, vs recommended enclosure and moderate moisture for ASA.
Should I use Prusament PC Space Grade or ASA for outdoor use?
For outdoor use, ASA is usually the better fit (Excellent UV resistance (outdoors indefinitely)). Choose Prusament PC Space Grade instead when extremely stiff.
