Strengths Comparison
SEBS Strengths
- Flexible, stretchy, and prints smoothly once dialed
- Much improved modern alternative to classic TPE
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
SEBS Caveats
- Hygroscopic
- Styrene fumes; low softening temp risks during drying
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 SEBS or PLA better for 3D printing?
SEBS is generally rated higher (Tier A) compared to PLA (Tier A). However, the best choice depends on your specific needs: SEBS is best for Flexible, stretchy, and prints smoothly once dialed, while PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between SEBS and PLA?
SEBS prints at 200-240°C nozzle / 40-60°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do SEBS and PLA need an enclosure?
SEBS: not needed. PLA: not needed.
Which is more beginner-friendly: SEBS or PLA?
