Strengths Comparison
Soft TPU Strengths
- Very flexible
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
Soft TPU Caveats
- Can tangle around drive gear
- Uncomfortable for wearables (doesn't breathe; gets sweaty)
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is Soft TPU or PETG better for 3D printing?
PETG is generally rated higher (Tier A) compared to Soft TPU (Tier C). However, the best choice depends on your specific needs: Soft TPU is best for Very flexible, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between Soft TPU and PETG?
Soft TPU prints at 200-220°C nozzle / 30-50°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do Soft TPU and PETG need an enclosure?
Soft TPU: not needed. PETG: optional.
Which is more beginner-friendly: Soft TPU or PETG?
Both Soft TPU and PETG are beginner-friendly options.
