Polycarbonate vs ASA
Compare Polycarbonate and ASA filaments side-by-side. See which one is best for your 3D printing project.
Polycarbonate
BPC
Very tough and stiff; doesn't shatter like PLA
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

Strengths Comparison
Polycarbonate Strengths
- Very tough and stiff; doesn't shatter like PLA
- High heat resistance (~150C softening region)
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
Polycarbonate Caveats
- Often overkill and high effort for typical use
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is Polycarbonate or ASA better for 3D printing?
ASA 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 ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between Polycarbonate and ASA?
Polycarbonate prints at 260-310°C nozzle / 90-120°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do Polycarbonate and ASA need an enclosure?
Polycarbonate: required. ASA: recommended.
Which is more beginner-friendly: Polycarbonate or ASA?
Neither is particularly beginner-friendly - both typically require an enclosure.
