PC-PBT vs ASA
Compare PC-PBT and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
PC-PBT vs ASA: PC-PBT is known for very easy pc-class filament (~260c), while ASA is known for excellent uv resistance (outdoors indefinitely). Both have recommended enclosure requirements; PC-PBT prints at higher nozzle temperatures (250-270°C vs 220-275°C). Choose PC-PBT for very easy pc-class filament (~260c), or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
PC-PBT
APolycarbonate + PBT alloy
Very easy PC-class filament (~260C), low warping, good surface quality
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-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)
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-PBT Caveats
- Feeding can be difficult unless spool is close/direct-fed
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
