Strengths Comparison

Carbon Fiber PETG Strengths

  • Greatly improved stability and support quality vs PETG
  • Stiffer than PETG; looks great (glossy walls)

TPU Strengths

  • Perfect layer adhesion; extremely impact resistant; nearly indestructible
  • Great for combat robots, tactical/rough-use parts
  • Rubber-like parts (gaskets, grips, bumpers, wheels)

Considerations

Carbon Fiber PETG Caveats

    TPU Caveats

    • Slow printing; retraction can cause jams (especially in Bowden setups)
    • Stringing is common
    • Very moisture sensitive; wet TPU prints poorly
