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 Polycarbonate Strengths
- Extremely stiff; useful where flex must be minimal
- Surprisingly affordable in some brands
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 Polycarbonate Caveats
- Feeding can be difficult unless spool is close/direct-fed
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 Carbon Fiber Polycarbonate or TPU better for 3D printing?
TPU is generally rated higher (Tier S) compared to Carbon Fiber Polycarbonate (Tier A).
