Carbon Fiber PLA vs PETG
Compare Carbon Fiber PLA and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
Carbon Fiber PLA vs PETG: Carbon Fiber PLA is known for sharper details, while PETG is known for tougher than pla. Carbon Fiber PLA is easier to print; PETG prints at higher nozzle temperatures (230-250°C vs 200-230°C). Choose Carbon Fiber PLA for sharper details, or PETG for tougher than pla.
Key differences at a glance
Carbon Fiber PLA
SPLA-CF
Sharper details, stabilizes cooling, low shrinkage
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
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 PLA Strengths
- Sharper details, stabilizes cooling, low shrinkage
- Matte finish, high dimensional accuracy, stiffer (but more brittle)
- Excellent-looking and accurate prints
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
Carbon Fiber PLA Caveats
- More brittle than PLA
- Typically limited color selection (often black)
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
