Strengths Comparison
Polycarbonate Strengths
- Very tough and stiff; doesn't shatter like PLA
- High heat resistance (~150C softening region)
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
Polycarbonate Caveats
- Often overkill and high effort for typical use
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 Polycarbonate or PLA better for 3D printing?
PLA is generally rated higher (Tier A) compared to Polycarbonate (Tier B). However, the best choice depends on your specific needs: Polycarbonate is best for Very tough and stiff; doesn't shatter like PLA, while PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between Polycarbonate and PLA?
Polycarbonate prints at 260-310°C nozzle / 90-120°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do Polycarbonate and PLA need an enclosure?
Polycarbonate: required. PLA: not needed.
Which is more beginner-friendly: Polycarbonate or PLA?
PLA is more beginner-friendly as it doesn't require an enclosure.
