ABS vs PLA
Compare ABS and PLA filaments side-by-side. See which one is best for your 3D printing project.
ABS
CAcrylonitrile Butadiene Styrene
Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

Strengths Comparison
ABS Strengths
- Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
- Outdoor capable for years (not fully UV proof but long-lasting)
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
ABS Caveats
- Warps heavily
- Strong fumes/off-gassing; enclosure recommended
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 ABS or PLA better for 3D printing?
PLA is generally rated higher (Tier A) compared to ABS (Tier C). However, the best choice depends on your specific needs: ABS is best for Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance, while PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between ABS and PLA?
ABS prints at 230-255°C nozzle / 95-110°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do ABS and PLA need an enclosure?
ABS: recommended. PLA: not needed.
Which is more beginner-friendly: ABS or PLA?
PLA is more beginner-friendly as it doesn't require an enclosure.
