PC (Polycarbonate) vs ASA
Compare PC (Polycarbonate) and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
PC (Polycarbonate) vs ASA: PC (Polycarbonate) is known for extremely stiff, while ASA is known for excellent uv resistance (outdoors indefinitely). PC (Polycarbonate) is easier to print; PC (Polycarbonate) prints at higher nozzle temperatures (270-275°C vs 220-275°C). Choose PC (Polycarbonate) for extremely stiff, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
PC (Polycarbonate)
-Extremely stiff; useful where flex must be minimal
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface
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
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
PC (Polycarbonate) Caveats
- Feeding can be difficult unless spool is close/direct-fed
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
