Improved hardness and rigidity

Spectrum PETG Carbon is a modified PET-G based filament blended with carbon fibres to significantly increase stiffness, hardness and tensile strength while maintaining low shrinkage and very good adhesion.

The addition of 10% carbon fibre also gives the model an aesthetic matt finish.

Note: Due to the high carbon fibre content, larger-diameter nozzles than the standard 0.4mm should be used. In addition, the addition of abrasive carbon fibres can lead to increased nozzle wear, which is why the use of hardened steel or ruby dies is recommended for processing Spectrum Carbon PETG.

Key Features of Spectrum Carbon PETG

• Modified PETG with 15% carbon fibre
• Improved Hardness & Stiffness
• Higher plasticising temperature
• Improved abrasion resistance
• VICAT - 80°C
• Significantly higher compressive strength compared to pure PETG
• Good mechanical properties
• Aesthetic, matt surface quality
• No shrinkage after cooling

Application of Spectrum Carbon PETG

• Parts that need to be very stiff and hard while maintaining dimensional accuracy
• Production of spacer components subjected to static pressure
• Concept and demo-prototyping of finished and semi-finished products
• Decorative parts (aesthetic qualities)
• Prototyping
