PETG vs PCTG
Compare PETG and PCTG filaments side-by-side. See which one is best for your 3D printing project.
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
PCTG
SPolycyclohexylene Dimethylene Terephthalate Glycol-modified
Tough, strong layer adhesion, minimal warping/sagging

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
PCTG Strengths
- Tough, strong layer adhesion, minimal warping/sagging
- Lower moisture uptake vs PETG; very easy printing for performance level
Considerations
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
PCTG Caveats
- Supports can be hard to remove
- Expensive and harder to find
Frequently Asked Questions
Is PETG or PCTG better for 3D printing?
PCTG is generally rated higher (Tier S) compared to PETG (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 PCTG is best for Tough, strong layer adhesion, minimal warping/sagging.
What are the temperature differences between PETG and PCTG?
PETG prints at 215-270°C nozzle / 70-90°C bed. PCTG prints at 230-260°C nozzle / 70-85°C bed.
Do PETG and PCTG need an enclosure?
PETG: optional. PCTG: optional.
Which is more beginner-friendly: PETG or PCTG?
Both PETG and PCTG are beginner-friendly options.
