SEBS vs ASA
Compare SEBS and ASA filaments side-by-side. See which one is best for your 3D printing project.
SEBS
AStyrene Ethylene Butylene Styrene
Flexible, stretchy, and prints smoothly once dialed

Strengths Comparison
SEBS Strengths
- Flexible, stretchy, and prints smoothly once dialed
- Much improved modern alternative to classic TPE
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
SEBS Caveats
- Hygroscopic
- Styrene fumes; low softening temp risks during drying
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is SEBS or ASA better for 3D printing?
SEBS is generally rated higher (Tier A) compared to ASA (Tier A). However, the best choice depends on your specific needs: SEBS is best for Flexible, stretchy, and prints smoothly once dialed, while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between SEBS and ASA?
SEBS prints at 200-240°C nozzle / 40-60°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do SEBS and ASA need an enclosure?
SEBS: not needed. ASA: recommended.
Which is more beginner-friendly: SEBS or ASA?
SEBS is more beginner-friendly as it doesn't require an enclosure.
