PETG vs PLA
Compare PETG and PLA filaments side-by-side so you can pick the right one for your 3D printing project.
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

Strengths Comparison
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
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 PETG or PLA better for 3D printing?
PETG is generally rated higher (Tier A) compared to PLA (Tier A). However, the best choice depends on your specific needs: PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use, while PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PETG and PLA?
PETG prints at 230-250°C nozzle / 70-90°C bed. PLA prints at 190-220°C nozzle / 50-60°C bed.
Do PETG and PLA need an enclosure?
PETG: optional. PLA: not needed.
Which is more beginner-friendly: PETG or PLA?
Both PETG and PLA are beginner-friendly options.
