Tough PLA vs ASA
Compare Tough PLA and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Tough PLA vs ASA: Tough PLA is known for prints like pla but resists higher temps, while ASA is known for excellent uv resistance (outdoors indefinitely). Tough PLA is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 200-230°C). Choose Tough PLA for prints like pla but resists higher temps, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
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
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
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
