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

Strengths Comparison
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
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
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is PLA or PETG better for 3D printing?
PLA is generally rated higher (Tier A) compared to PETG (Tier A). However, the best choice depends on your specific needs: PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between PLA and PETG?
PLA prints at 185-235°C nozzle / 50-60°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do PLA and PETG need an enclosure?
PLA: not needed. PETG: optional.
Which is more beginner-friendly: PLA or PETG?
Both PLA and PETG are beginner-friendly options.
