Tough PLA vs ASA
Compare Tough PLA and ASA filaments side-by-side. See which one is best for your 3D printing project.
Tough PLA
SPLA + PBT alloy
Prints like PLA but resists higher temps, impacts, and shattering
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

Strengths Comparison
Tough PLA Strengths
- Prints like PLA but resists higher temps, impacts, and shattering
- Straight upgrade for many light-duty projects
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
Tough PLA Caveats
- Labeling in market is inconsistent (many overlapping brand names)
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is Tough PLA or ASA better for 3D printing?
Tough PLA is generally rated higher (Tier S) compared to ASA (Tier A). However, the best choice depends on your specific needs: Tough PLA is best for Prints like PLA but resists higher temps, impacts, and shattering, while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between Tough PLA and ASA?
Tough PLA prints at 200-230°C nozzle / 50-70°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do Tough PLA and ASA need an enclosure?
Tough PLA: not needed. ASA: recommended.
Which is more beginner-friendly: Tough PLA or ASA?
Tough PLA is more beginner-friendly as it doesn't require an enclosure.
