PVB vs PETG
Compare PVB and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
PVB vs PETG: PVB is known for alcohol smoothing (isopropanol) can fuse layers and create..., while PETG is known for tougher than pla. PVB is easier to print; PETG prints at higher nozzle temperatures (230-250°C vs 190-220°C). Choose PVB for alcohol smoothing (isopropanol) can fuse layers and create..., or PETG for tougher than pla.
Key differences at a glance
PVB
SPPolyvinyl Butyral
Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
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
PVB Strengths
- Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
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
PVB Caveats
- Alcohol vapor can fuse the spool itself (example: spool stuck together)
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
