PVDF vs ASA
Compare PVDF and ASA filaments side-by-side so you can pick the right one for your 3D printing project.
PVDF vs ASA: PVDF is known for prints like petg but tougher, while ASA is known for excellent uv resistance (outdoors indefinitely). Both have recommended enclosure requirements; PVDF is less moisture-sensitive; ASA prints at higher nozzle temperatures (220-275°C vs 220-260°C). Choose PVDF for prints like petg but tougher, or ASA for excellent uv resistance (outdoors indefinitely).
Key differences at a glance
PVDF
FPolyvinylidene Fluoride / Kynar
Prints like PETG but tougher; very durable; hydrophobic (no drying)
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
PVDF Strengths
- Prints like PETG but tougher; very durable; hydrophobic (no drying)
- Extremely chemically resistant
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
PVDF Caveats
- If overheated, decomposes into highly toxic chemicals (including hydrogen cyanide and hydrofluoric acid)
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
