PPS vs TPU
Compare PPS and TPU filaments side-by-side. See which one is best for your 3D printing project.
PPS
CPolyphenylene Sulfide
Exceptional chemical resistance (claimed near-inert below ~200C); solid performance for chemical environments
TPU

Strengths Comparison
PPS Strengths
- Exceptional chemical resistance (claimed near-inert below ~200C); solid performance for chemical environments
TPU Strengths
- Perfect layer adhesion; extremely impact resistant; nearly indestructible
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
PPS Caveats
- Expensive (~$200/kg) and still high-demands; niche justification
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
Is PPS or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to PPS (Tier C). However, the best choice depends on your specific needs: PPS is best for Exceptional chemical resistance (claimed near-inert below ~200C); solid performance for chemical environments, while TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between PPS and TPU?
PPS prints at 300-340°C nozzle / 120-150°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do PPS and TPU need an enclosure?
PPS: required. TPU: not needed.
Which is more beginner-friendly: PPS or TPU?
TPU is more beginner-friendly as it doesn't require an enclosure.
