PVDF vs PLA
Compare PVDF and PLA 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)
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

Strengths Comparison
PVDF Strengths
- Prints like PETG but tougher; very durable; hydrophobic (no drying)
- Extremely chemically resistant
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PVDF Caveats
- If overheated, decomposes into highly toxic chemicals (including hydrogen cyanide and hydrofluoric acid)
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Frequently Asked Questions
Is PVDF or PLA better for 3D printing?
PLA 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 PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PVDF and PLA?
PVDF prints at 220-260°C nozzle / 70-90°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do PVDF and PLA need an enclosure?
PVDF: recommended. PLA: not needed.
Which is more beginner-friendly: PVDF or PLA?
PLA is more beginner-friendly as it doesn't require an enclosure.
