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

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)

Considerations

Ultrafuse PA6 GF30 Caveats

  • Higher print temps; hardware wear if not equipped

TPU Caveats

  • Slow printing; retraction can cause jams (especially in Bowden setups)
  • Stringing is common
  • Very moisture sensitive; wet TPU prints poorly

Frequently Asked Questions

What is the difference between Ultrafuse PA6 GF30 and TPU?
Ultrafuse PA6 GF30 prints at 270°C nozzle / 100°C bed (No enclosure, low moisture sensitivity). TPU prints at 200-240°C nozzle / 30-60°C bed (No enclosure, high moisture sensitivity).
Is Ultrafuse PA6 GF30 or TPU 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 TPU is suited to excellent layer adhesion.
Which prints at a higher temperature, Ultrafuse PA6 GF30 or TPU?
Ultrafuse PA6 GF30 prints at a higher temperature (270°C nozzle vs 200-240°C for TPU).
Is Ultrafuse PA6 GF30 or TPU better for beginners?
Ultrafuse PA6 GF30 is better for beginners: enclosure is no and moisture sensitivity is low, vs no enclosure and high moisture for TPU.
Should I use Ultrafuse PA6 GF30 or TPU for flexible parts?
For flexible parts, TPU is usually the better fit (Excellent layer adhesion). Choose Ultrafuse PA6 GF30 instead when massively stiffer/tougher/more heat & abrasion resistant than nylon.
