PVB vs PETG
Compare PVB and PETG filaments side-by-side. See which one is best for your 3D printing project.
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

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
Frequently Asked Questions
Is PVB or PETG better for 3D printing?
PETG is generally rated higher (Tier A) compared to PVB (Tier SPECIAL). However, the best choice depends on your specific needs: PVB is best for Alcohol smoothing (isopropanol) can fuse layers and create a slick surface, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between PVB and PETG?
PVB prints at 190-220°C nozzle / 50-70°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do PVB and PETG need an enclosure?
PVB: not needed. PETG: optional.
Which is more beginner-friendly: PVB or PETG?
Both PVB and PETG are beginner-friendly options.
