Prusament PEI 1010 vs PETG
Compare Prusament PEI 1010 and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
Prusament PEI 1010 vs PETG: Prusament PEI 1010 is known for very strong, while PETG is known for tougher than pla. Prusament PEI 1010 is easier to print; Prusament PEI 1010 prints at higher nozzle temperatures (430°C vs 230-250°C). Choose Prusament PEI 1010 for very strong, or PETG for tougher than pla.
Key differences at a glance
Prusament PEI 1010
-Very strong, stable, and safe superpolymer; low thermal expansion enables good dimensional accuracy
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
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
Prusament PEI 1010 Strengths
- Very strong, stable, and safe superpolymer; low thermal expansion enables good dimensional accuracy
- Once setup is met, prints relatively friendly
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
Prusament PEI 1010 Caveats
- Setup requirements too extreme for S tier
- Cannot print on PEI-coated plate repeatedly (bonding/plate damage risk)
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
