Esun PLA vs ASA
Compare Esun PLA and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Esun PLA vs ASA: Esun PLA is known for easiest to print, while ASA is known for excellent uv resistance (outdoors indefinitely). Esun PLA is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 210°C). Choose Esun PLA for easiest to print, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
Esun PLA
-Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
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
Esun PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
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
Esun PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
