Filament PM PETG vs TPU
Compare Filament PM PETG and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
Filament PM PETG vs TPU: Filament PM PETG is known for tougher than pla, while TPU is known for excellent layer adhesion. Both have no enclosure requirements; Filament PM PETG is less moisture-sensitive; Filament PM PETG prints at higher nozzle temperatures (240°C vs 200-240°C). Choose Filament PM PETG for tougher than pla, or TPU for excellent layer adhesion.
Key differences at a glance
Filament PM PETG
-Tougher than PLA, higher temp tolerance, more durable in real-world use
TPU
SThermoplastic Polyurethane
Excellent layer adhesion; extremely impact resistant; highly durable
Detailed Comparison
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
Filament PM 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
Filament PM 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
