Strengths Comparison
Carbon Fiber PETG Strengths
- Greatly improved stability and support quality vs PETG
- Stiffer than PETG; looks great (glossy walls)
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
Carbon Fiber PETG Caveats
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is Carbon Fiber PETG or ASA better for 3D printing?
Carbon Fiber PETG is generally rated higher (Tier S) compared to ASA (Tier A). However, the best choice depends on your specific needs: Carbon Fiber PETG is best for Greatly improved stability and support quality vs PETG, while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
