PVDF vs PETG
Compare PVDF and PETG 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)
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use

Strengths Comparison
PVDF Strengths
- Prints like PETG but tougher; very durable; hydrophobic (no drying)
- Extremely chemically resistant
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
Considerations
PVDF Caveats
- If overheated, decomposes into highly toxic chemicals (including hydrogen cyanide and hydrofluoric acid)
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is PVDF or PETG better for 3D printing?
PETG 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 PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between PVDF and PETG?
PVDF prints at 220-260°C nozzle / 70-90°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do PVDF and PETG need an enclosure?
PVDF: recommended. PETG: optional.
Which is more beginner-friendly: PVDF or PETG?
PETG is more beginner-friendly as it doesn't require an enclosure.
