Prusament ASA vs PLA
Compare Prusament ASA and PLA filaments side-by-side so you can pick the right one for your 3D printing project.
Prusament ASA vs PLA: Prusament ASA is known for excellent uv resistance (outdoors indefinitely), while PLA is known for easiest to print. Both have no enclosure requirements; Prusament ASA is less moisture-sensitive; Prusament ASA prints at higher nozzle temperatures (260°C vs 190-220°C). Choose Prusament ASA for excellent uv resistance (outdoors indefinitely), or PLA for easiest to print.
Key differences at a glance
Prusament ASA
-Excellent UV resistance (outdoors indefinitely), tough, matte surface
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
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
Prusament 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)
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
Prusament ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
