Ultrafuse PA6 GF30 vs TPU
Compare Ultrafuse PA6 GF30 and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
Ultrafuse PA6 GF30 vs TPU: Ultrafuse PA6 GF30 is known for massively stiffer/tougher/more heat & abrasion resistant than nylon, while TPU is known for excellent layer adhesion. Both have no enclosure requirements; Ultrafuse PA6 GF30 is less moisture-sensitive; Ultrafuse PA6 GF30 prints at higher nozzle temperatures (270°C vs 200-240°C). Choose Ultrafuse PA6 GF30 for massively stiffer/tougher/more heat & abrasion resistant than nylon, or TPU for excellent layer adhesion.

Detailed Comparison
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
