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

Ultrafuse PA6 GF30 Strengths

  • Massively stiffer/tougher/more heat & abrasion resistant than nylon
  • Warping reduced enough to be fairly easy to print (with correct setup)
  • Viable alternative to machined aluminum for some parts

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

Ultrafuse PA6 GF30 Caveats

  • Higher print temps; hardware wear if not equipped

PETG Caveats

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

Frequently Asked Questions

What is the difference between Ultrafuse PA6 GF30 and PETG?
Ultrafuse PA6 GF30 prints at 270°C nozzle / 100°C bed (No enclosure, low moisture sensitivity). PETG prints at 230-250°C nozzle / 70-90°C bed (Optional enclosure, moderate moisture sensitivity).
Is Ultrafuse PA6 GF30 or PETG stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Ultrafuse PA6 GF30 is suited to massively stiffer/tougher/more heat & abrasion resistant than nylon, while PETG is suited to tougher than pla.
Which prints at a higher temperature, Ultrafuse PA6 GF30 or PETG?
Ultrafuse PA6 GF30 prints at a higher temperature (270°C nozzle vs 230-250°C for PETG).
Is Ultrafuse PA6 GF30 or PETG better for beginners?
Ultrafuse PA6 GF30 is better for beginners: enclosure is no and moisture sensitivity is low, vs optional enclosure and moderate moisture for PETG.
Should I use Ultrafuse PA6 GF30 or PETG for high-temperature parts?
For high-temperature parts, Ultrafuse PA6 GF30 is usually the better fit (Massively stiffer/tougher/more heat & abrasion resistant than nylon). Choose PETG instead when tougher than pla.
