PPS vs PETG
Compare PPS and PETG 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
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use

Strengths Comparison
PPS Strengths
- Exceptional chemical resistance (claimed near-inert below ~200C); solid performance for chemical environments
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
Considerations
PPS Caveats
- Expensive (~$200/kg) and still high-demands; niche justification
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is PPS or PETG better for 3D printing?
PETG 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 PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between PPS and PETG?
PPS prints at 300-340°C nozzle / 120-150°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do PPS and PETG need an enclosure?
PPS: required. PETG: optional.
Which is more beginner-friendly: PPS or PETG?
PETG is more beginner-friendly as it doesn't require an enclosure.
