Carbon Fiber PETG vs TPU
Compare Carbon Fiber PETG and TPU filaments side-by-side so you can pick the right one for your 3D printing project.
Carbon Fiber PETG vs TPU: Carbon Fiber PETG is known for greatly improved stability and support quality vs petg, while TPU is known for excellent layer adhesion. TPU is easier to print; Carbon Fiber PETG is less moisture-sensitive; Carbon Fiber PETG prints at higher nozzle temperatures (230-260°C vs 200-240°C). Choose Carbon Fiber PETG for greatly improved stability and support quality vs petg, or TPU for excellent layer adhesion.

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
Carbon Fiber PETG Strengths
- Greatly improved stability and support quality vs PETG
- Stiffer than PETG; looks great (glossy walls)
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
Carbon Fiber 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
