PLA vs ABS
Compare PLA and ABS filaments side-by-side so you can pick the right one 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

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
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
- Good impact toughness for the price
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 plus ventilation recommended
- Poor UV resistance; yellows and gets brittle outdoors (ASA is the better outdoor/UV choice)
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 190-220°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.
