Carbon fiber is a very strong, light material, and is a well-known method to make a matrix material much stronger. eSun has incorporated carbon fiber into this material to make it very stiff. It's tougher to print than ABS, as it requires a printer capable of even higher temperatures and a very hot bed, but if you are requiring a strong 3D printed model, this is the material for you.


  • Environmentally friendly, nylon based, 20% carbon fiber
  • Prints smoothly, odourless, with a matte finish
  • High strength, high rigidity, tough, wear resistant
  • Lower shrink rate and distortion compared to nylon
  • Good flame resistance, with flame-retardant level UL94-V2
  • A stainless steel nozzle is strongly recommended. It's a fairly abrasive filament that will wear out your nozzle.


  • 1.75mm nominal diameter (spec'd +/- 0.05, but is in practice closer to +/- 0.03)
  • 1kg spools on LARGE diameter (easy unspooling) reels, vacuum sealed with desiccant
  • Suggested build parameters:
    • Print temperature 240-260 ℃
    • Base temperature: 80 °C
    • Print speed: 30-60 mm/s
    • Movement speed: 90-150 mm/s

Material Characteristics:

  • 85MPa Tensile Strength (vs 65MPa for PLA+)
  • 16% elongation at breaking point (vs 12% for PLA+)
  • 15.5 KJ/m² IZOD impact strength (vs 4 KJ/m² for PLA+)

ESun is a top supplier of 3D printer filament, and we're happy to be carrying their inventory. They are not some fly-by-night operation; eSun is an active part of the 3D printer community, and you'll often see them represented at Maker Faires and 3D Printer Expos. We've even been to their labs at the Shenzhen University grounds where they develop and test their product. They take excellent care with their production methods, and each spool comes vacuum sealed in a pouch with moisture-absorbing desiccant.

In short, eSun knows their stuff. We're extremely happy with the quality and consistency of their material.
