Fillamentum ABS vs ASA
Compare Fillamentum ABS and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
Fillamentum ABS vs ASA: Fillamentum ABS is known for fast printing, while ASA is known for excellent uv resistance (outdoors indefinitely). Fillamentum ABS is easier to print; ASA prints at higher nozzle temperatures (220-275°C vs 240°C). Choose Fillamentum ABS for fast printing, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
Fillamentum ABS
-Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
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
Fillamentum ABS Strengths
- Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
- Good impact toughness for the price
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
Fillamentum ABS Caveats
- Warps heavily
- Strong fumes/off-gassing; enclosure plus ventilation recommended
- Poor UV resistance; yellows and gets brittle outdoors (ASA is the better outdoor/UV choice)
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
