PVB vs PLA
Compare PVB and PLA 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
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

Strengths Comparison
PVB Strengths
- Alcohol smoothing (isopropanol) can fuse layers and create a slick surface
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PVB Caveats
- Alcohol vapor can fuse the spool itself (example: spool stuck together)
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Frequently Asked Questions
Is PVB or PLA better for 3D printing?
PLA 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 PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PVB and PLA?
PVB prints at 190-220°C nozzle / 50-70°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do PVB and PLA need an enclosure?
PVB: not needed. PLA: not needed.
Which is more beginner-friendly: PVB or PLA?
