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
SEBS Strengths
- Flexible, stretchy, and prints smoothly once dialed
- Much improved modern alternative to classic TPE
TPU Strengths
- Excellent layer adhesion; extremely impact resistant; highly durable
- Great for combat robots, tactical/rough-use parts
- Rubber-like parts (gaskets, grips, bumpers, wheels)
Considerations
SEBS Caveats
- Hygroscopic
- Styrene fumes; low softening temp risks during drying
TPU Caveats
- Slow printing; retraction can cause jams (especially in Bowden setups)
- Stringing is common
- Very moisture sensitive; wet TPU prints poorly
Frequently Asked Questions
What is the difference between SEBS and TPU?
SEBS prints at 200-240°C nozzle / 40-60°C bed (No enclosure, high moisture sensitivity). TPU prints at 200-240°C nozzle / 30-60°C bed (No enclosure, high moisture sensitivity).
Is SEBS or TPU stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, SEBS is suited to flexible, while TPU is suited to excellent layer adhesion.
Which prints at a higher temperature, SEBS or TPU?
Both print at similar nozzle temperatures (200-240°C vs 200-240°C).
Is SEBS or TPU better for beginners?
Both are similarly approachable: SEBS (no enclosure, high moisture) and TPU (no enclosure, high moisture).
Should I use SEBS or TPU for flexible parts?
For flexible parts, SEBS is usually the better fit (Flexible). Choose TPU instead when excellent layer adhesion.
