PC-PBT vs PLA
Compare PC-PBT and PLA 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
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

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)
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PC-PBT Caveats
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 PC-PBT or PLA better for 3D printing?
PC-PBT is generally rated higher (Tier A) compared to PLA (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 PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PC-PBT and PLA?
PC-PBT prints at 250-270°C nozzle / 80-100°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do PC-PBT and PLA need an enclosure?
PC-PBT: recommended. PLA: not needed.
Which is more beginner-friendly: PC-PBT or PLA?
PLA is more beginner-friendly as it doesn't require an enclosure.
