PETG vs TPU
Compare PETG and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
TPU
SThermoplastic Polyurethane
Excellent layer adhesion; extremely impact resistant; highly durable

Strengths Comparison
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
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
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
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
Is PETG or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to PETG (Tier A). However, the best choice depends on your specific needs: PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use, while TPU is best for Excellent layer adhesion; extremely impact resistant; highly durable.
What are the temperature differences between PETG and TPU?
PETG prints at 230-250°C nozzle / 70-90°C bed. TPU prints at 200-240°C nozzle / 30-60°C bed.
Do PETG and TPU need an enclosure?
PETG: optional. TPU: not needed.
Which is more beginner-friendly: PETG or TPU?
Both PETG and TPU are beginner-friendly options.
