PVDF vs ASA
Compare PVDF and ASA filaments side-by-side. See which one is best for your 3D printing project.
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

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
Frequently Asked Questions
Is PVDF or ASA better for 3D printing?
ASA is generally rated higher (Tier A) compared to PVDF (Tier F). However, the best choice depends on your specific needs: PVDF is best for Prints like PETG but tougher; very durable; hydrophobic (no drying), while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between PVDF and ASA?
PVDF prints at 220-260°C nozzle / 70-90°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do PVDF and ASA need an enclosure?
PVDF: recommended. ASA: recommended.
Which is more beginner-friendly: PVDF or ASA?
Neither is particularly beginner-friendly - both typically require an enclosure.
