PC (Polycarbonate) vs PLA
Compare PC (Polycarbonate) and PLA filaments side-by-side so you can pick the right one for your 3D printing project.
PC (Polycarbonate) vs PLA: PC (Polycarbonate) is known for extremely stiff, while PLA is known for easiest to print. Both have no enclosure requirements; PC (Polycarbonate) is less moisture-sensitive; PC (Polycarbonate) prints at higher nozzle temperatures (270-275°C vs 190-220°C). Choose PC (Polycarbonate) for extremely stiff, or PLA for easiest to print.
Key differences at a glance
PC (Polycarbonate)
-Extremely stiff; useful where flex must be minimal
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
Detailed Comparison
Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.
Strengths Comparison
PC (Polycarbonate) Strengths
- Extremely stiff; useful where flex must be minimal
- Surprisingly affordable in some brands
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PC (Polycarbonate) Caveats
- Feeding can be difficult unless spool is close/direct-fed
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
