PC-PBT vs ASA
Compare PC-PBT and ASA 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
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

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
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is PC-PBT or ASA better for 3D printing?
PC-PBT is generally rated higher (Tier A) compared to ASA (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 ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between PC-PBT and ASA?
PC-PBT prints at 250-270°C nozzle / 80-100°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do PC-PBT and ASA need an enclosure?
PC-PBT: recommended. ASA: recommended.
Which is more beginner-friendly: PC-PBT or ASA?
Neither is particularly beginner-friendly - both typically require an enclosure.
