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

Strengths Comparison
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
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)
Considerations
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
ABS Caveats
- Warps heavily
- Strong fumes/off-gassing; enclosure recommended
Frequently Asked Questions
Is PLA or ABS 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: PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal, while ABS is best for Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance.
What are the temperature differences between PLA and ABS?
PLA prints at 185-235°C nozzle / 50-60°C bed. ABS prints at 230-255°C nozzle / 95-110°C bed.
Do PLA and ABS need an enclosure?
PLA: not needed. ABS: recommended.
Which is more beginner-friendly: PLA or ABS?
PLA is more beginner-friendly as it doesn't require an enclosure.
