eSUN PETG-CF Carbon Fiber Filament

eSUN PETG-CF 3D Printer Filament, 2x Stronger Carbon Fiber!

2 min reading time

eSUN PETG-CF is a 3D printing filament that combines the excellent properties of PETG with the strength of carbon fiber, increasing Flexural Modulus by 203% and Flexural Strength by 190% compared to standard PETG. It is suitable for engineering applications, prototyping, automotive parts, and electronics.

What is PETG-CF?

Carbon Fiber is a reinforcing fiber renowned for its strength, light weight, chemical resistance, and high heat resistance. eSUN has combined carbon fiber with PETG to create a new material called eSUN PETG-CF, which takes strength and durability properties to the next level.

Previously, eSUN launched several carbon fiber materials like PLA-CF, ABS-CF, PA-CF, PA12-CF, and PA12+CF. Today, the carbon fiber family expands even further with PETG-CF!

Why choose eSUN PETG-CF?

1. 2 Times Stronger than Regular PETG (High Strength & High Rigidity)

Compared to regular PETG, eSUN PETG-CF offers significantly outstanding performance:

  • Flexural Modulus: 2,500 MPa — an increase of up to 203%
  • Flexural Strength: Increased by up to 190%

These figures mean that parts printed with PETG-CF are noticeably stronger and more resistant to bending.

2. Easy to Print, No Hassles (Excellent Printability)

eSUN's PETG-CF is designed for easy printing, reducing common 3D printing issues:

  • Reduced Stringing
  • Reduced Oozing
  • Reduced Nozzle Clogging
  • Minimal Warping — excellent bed adhesion, no distortion

3. Better Chemical Resistance

PETG already possesses good water and chemical resistance. When reinforced with carbon fiber, its stability performance is further enhanced, offering better resistance to corrosive substances. This makes it suitable for applications exposed to harsh environments.

4. Premium Frosted Surface Good Texture

Unlike typical carbon fiber materials that are often only black, eSUN PETG-CF comes in a variety of color options:

  • 🖤 DARK GREY
  • 🥉 ANTIQUE BRASS
  • 🔴 BLACK RED
  • 🟢 DARK GREEN
  • 🔵 DARK BLUE

The printed parts have a Matte Frosted (matte and beautiful) surface that looks premium, ideal for those who desire both aesthetics and performance.

Printing Precautions

Since PETG-CF contains carbon fiber, there are a few things to consider:

  • 🔩 Use a Hardened Steel Nozzle — Carbon fiber can cause faster wear on regular nozzles.
  • 💧 Beware of Moisture — PETG-CF filament absorbs moisture easily. It is recommended to dry it before use at 65°C for at least 8 hours.

Summary

eSUN PETG-CF is an excellent choice for 3D printers seeking strength, durability, and aesthetics all at once. With an increase in Flexural Modulus by 203% and Flexural Strength by 190% compared to regular PETG, PETG-CF is a great option for high-performance engineering applications.

With a variety of color options and a beautiful Matte Frosted surface, PETG-CF from eSUN is both a strong and beautiful material!
