Spectrum PET-G Carbon is a modified PET-G filament reinforced with carbon fibers (10%), designed for demanding technical and structural applications. The carbon reinforcement significantly improves mechanical strength, stiffness, and compressive resistance, while maintaining PET-G’s benefits such as low shrinkage and excellent build plate adhesion.

The added carbon fibers create a matte, professional surface, making this filament suitable for functional as well as visible components.

Printing Recommendations

• use nozzles larger than 0.4 mm

• carbon fibers are abrasive – stainless steel or hardened nozzles recommended

Key Features

• increased hardness and stiffness vs. pure PET-G

• higher softening temperature

• improved abrasion resistance

• VICAT temperature: 80 °C

• high compressive strength

• excellent mechanical properties

• matte surface with high aesthetic quality

• zero shrinkage after cooling

Applications

• rigid and dimensionally accurate parts

• spacers under static load

• functional and concept prototyping

• decorative and visible components

• external structural elements

Packaging

• filament wound on a transparent spool

• labeled with material type, diameter and print temperature

• vacuum sealed with moisture absorber

• original Spectrum Filaments packaging

VERIFY YOUR SPOOL – Quality Control

Each 1 mm of filament is continuously measured in two axes with ±0.8 µm accuracy.

Online spool verification includes:

• diameter graph along the entire spool

• average diameter

• ovality

• standard deviation
