PPS vs ASA
Compare PPS and ASA 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
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

Strengths Comparison
PPS Strengths
- Exceptional chemical resistance (claimed near-inert below ~200C); solid performance for chemical environments
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
PPS Caveats
- Expensive (~$200/kg) and still high-demands; niche justification
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is PPS or ASA better for 3D printing?
ASA 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 ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between PPS and ASA?
PPS prints at 300-340°C nozzle / 120-150°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do PPS and ASA need an enclosure?
PPS: required. ASA: recommended.
Which is more beginner-friendly: PPS or ASA?
Neither is particularly beginner-friendly - both typically require an enclosure.
