Spectrum PETG Carbon Filament BLACK 1.75mm 1kg

Description

Spectrum PETG Carbon Filament BLACK 1.75mm 1kg — Carbon-fiber reinforced PETG for rigid, matte, dimensionally accurate prints

Spectrum PETG Carbon Filament BLACK 1.75mm 1kg is a modified PETG-based filament blended with carbon fibers to provide considerably higher rigidity, hardness, and tensile resistance than standard PET-G, while retaining the low shrinkage and very good bed adhesion typical of pure PETG. Spectrum PETG Carbon Filament contains 10% carbon fiber, which helps create a matte, carbon-look surface finish and improves the visual quality of printed parts.

Key Benefits at a Glance

• Higher rigidity and hardness: Designed to be stiffer and harder than pure PET-G.
• Carbon-look matte finish: The carbon fiber content gives printed parts a matte, technical appearance.
• Good dimensional stability: Low shrinkage and no shrinkage after cooling help maintain part accuracy.
• Improved compression and abrasion resistance: A strong option for rigid parts exposed to static loads and wear.

Main Material Characteristics

• Improved hardness and rigidity compared to pure PET-G
• Higher plasticisation temperature compared to pure PET-G
• Improved abrasion resistance
• Much higher compression resistance compared to pure PET-G
• Good mechanical properties
• High aesthetic matte surface quality
• No shrinkage after cooling

Recommended Printing Settings

• Nozzle temperature: 230–255°C
• Heated bed temperature: 60–80°C
• Recommended printing speed: 30–120 mm/s
• Cooling fan: 75–100%
• Closed chamber: Not necessary
• Nozzle type: Ruby or hardened nozzle recommended
• Additional adhesion aids: Not required, but may be used if needed

Important Printing Note

Because of the carbon fiber content, Spectrum recommends using nozzle diameters larger than the standard 0.4 mm. Carbon fiber can also cause brass nozzle wear over time, so a stainless steel, hardened, or ruby nozzle is the better choice for longer-term use.

Ideal Applications

• Rigid technical parts that need high dimensional accuracy
• Spacer components subject to static compressive loads
• Functional parts where higher stiffness and surface quality are important
• Technical prints that benefit from a matte carbon-look finish

Why You’ll Love It

Spectrum PETG Carbon Filament is a practical choice when standard PETG is too soft or visually plain for the job. Spectrum PETG Carbon Filament offers a stiffer, harder, more technical alternative with a matte carbon appearance, good dimensional stability, and stronger resistance to compression and abrasion, making it especially useful for rigid functional parts and technical-looking prints.
