PVDF vs TPU
Compare PVDF and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
PVDF vs TPU: PVDF is known for prints like petg but tougher, while TPU is known for excellent layer adhesion. TPU is easier to print; PVDF is less moisture-sensitive; PVDF prints at higher nozzle temperatures (220-260°C vs 200-240°C). Choose PVDF for prints like petg but tougher, or TPU for excellent layer adhesion.
Key differences at a glance
PVDF
FPolyvinylidene Fluoride / Kynar
Prints like PETG but tougher; very durable; hydrophobic (no drying)
TPU
SThermoplastic Polyurethane
Excellent layer adhesion; extremely impact resistant; highly durable
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
TPU Strengths
- Excellent layer adhesion; extremely impact resistant; highly durable
- 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
