PPS vs PLA
Compare PPS and PLA 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
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

Strengths Comparison
PPS Strengths
- Exceptional chemical resistance (claimed near-inert below ~200C); solid performance for chemical environments
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PPS Caveats
- Expensive (~$200/kg) and still high-demands; niche justification
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Frequently Asked Questions
Is PPS or PLA better for 3D printing?
PLA is generally rated higher (Tier A) 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 PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PPS and PLA?
PPS prints at 300-340°C nozzle / 120-150°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do PPS and PLA need an enclosure?
PPS: required. PLA: not needed.
Which is more beginner-friendly: PPS or PLA?
PLA is more beginner-friendly as it doesn't require an enclosure.
