Prusament PVB vs TPU
Compare Prusament PVB and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
Prusament PVB vs TPU: Prusament PVB is known for alcohol smoothing (isopropanol) can fuse layers and create..., while TPU is known for excellent layer adhesion. Both have no enclosure requirements; Prusament PVB is less moisture-sensitive; TPU prints at higher nozzle temperatures (200-240°C vs 215°C). Choose Prusament PVB for alcohol smoothing (isopropanol) can fuse layers and create..., or TPU for excellent layer adhesion.
Key differences at a glance
Prusament PVB
-Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
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
Prusament PVB Strengths
- Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
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
Prusament PVB Caveats
- Alcohol vapor can fuse the spool itself (example: spool stuck together)
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
