PLA vs Tough PLA
Compare PLA and Tough PLA 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
Tough PLA
SPLA + PBT alloy
Prints like PLA but resists higher temps, impacts, and shattering

Strengths Comparison
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Tough PLA Strengths
- Prints like PLA but resists higher temps, impacts, and shattering
- Straight upgrade for many light-duty projects
Considerations
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Tough PLA Caveats
- Labeling in market is inconsistent (many overlapping brand names)
