Strengths Comparison
SEBS Strengths
- Flexible, stretchy, and prints smoothly once dialed
- Much improved modern alternative to classic TPE
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
Considerations
SEBS Caveats
- Hygroscopic
- Styrene fumes; low softening temp risks during drying
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is SEBS or PETG better for 3D printing?
SEBS is generally rated higher (Tier A) compared to PETG (Tier A). However, the best choice depends on your specific needs: SEBS is best for Flexible, stretchy, and prints smoothly once dialed, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between SEBS and PETG?
SEBS prints at 200-240°C nozzle / 40-60°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do SEBS and PETG need an enclosure?
SEBS: not needed. PETG: optional.
Which is more beginner-friendly: SEBS or PETG?
Both SEBS and PETG are beginner-friendly options.
