Strengths Comparison

Ultrafuse PET-CF15 Strengths

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

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 PET-CF15 Caveats

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

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 PET-CF15 and TPU?
Ultrafuse PET-CF15 prints at 270°C nozzle / 75°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 PET-CF15 or TPU stronger?
