PC-PBT vs PETG
Compare PC-PBT and PETG filaments side-by-side. See which one is best for your 3D printing project.
PC-PBT
APolycarbonate + PBT alloy
Very easy PC-class filament (~260C), low warping, good surface quality
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use

Strengths Comparison
PC-PBT Strengths
- Very easy PC-class filament (~260C), low warping, good surface quality
- Maintains shatter resistance and stays durable in cold (won't get brittle)
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
PC-PBT Caveats
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is PC-PBT or PETG better for 3D printing?
PC-PBT is generally rated higher (Tier A) compared to PETG (Tier A). However, the best choice depends on your specific needs: PC-PBT is best for Very easy PC-class filament (~260C), low warping, good surface quality, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between PC-PBT and PETG?
PC-PBT prints at 250-270°C nozzle / 80-100°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do PC-PBT and PETG need an enclosure?
PC-PBT: recommended. PETG: optional.
Which is more beginner-friendly: PC-PBT or PETG?
PETG is more beginner-friendly as it doesn't require an enclosure.
