PVDF vs TPU
Compare PVDF and TPU 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)
TPU
SThermoplastic Polyurethane
Perfect layer adhesion; extremely impact resistant; nearly indestructible

Strengths Comparison
PVDF Strengths
- Prints like PETG but tougher; very durable; hydrophobic (no drying)
- Extremely chemically resistant
TPU Strengths
- Perfect layer adhesion; extremely impact resistant; nearly indestructible
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
PVDF Caveats
- If overheated, decomposes into highly toxic chemicals (including hydrogen cyanide and hydrofluoric acid)
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
Frequently Asked Questions
Is PVDF or TPU better for 3D printing?
TPU is generally rated higher (Tier S) 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 TPU is best for Perfect layer adhesion; extremely impact resistant; nearly indestructible.
What are the temperature differences between PVDF and TPU?
PVDF prints at 220-260°C nozzle / 70-90°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do PVDF and TPU need an enclosure?
PVDF: recommended. TPU: not needed.
Which is more beginner-friendly: PVDF or TPU?
TPU is more beginner-friendly as it doesn't require an enclosure.
