Spectrum ReFill PET-G Carbon

Filament Spectrum ReFill PET-G Carbon

The Spectrum ReFill PET-G Carbon filament is an advanced printing material wound on an eco-friendly cardboard core, combining PET-G properties with carbon fibre additives. This refill version is designed for producing objects that require increased rigidity, hardness, and tensile strength without unwanted shrinkage. Thanks to its 10% carbon fibre content, it provides a matte surface that enhances the aesthetics of printed objects.

Spool Compatibility

The refill version of the filament is fully compatible with reusable spools, such as those from Bambu Lab.

TIP: If you don't have a Bambu Lab spool, you can download and print a simple spool model from the Spectrum website or purchase a Spectrum ReFill Spool.

Key Features

• Increased Rigidity and Hardness: Offers higher mechanical resistance and strength compared to pure PET-G.
• Wear Resistance: Designed to withstand wear, making it suitable for long-term use.
• High Aesthetic Quality: Matte surface enhances visual appeal.
• No Shrinkage After Cooling: Ensures dimensional stability of printed parts.
• High Plastification Temperature: Enables use in applications with higher temperature requirements.
• VICAT Softening Temperature: 80°C, ensuring the material maintains its strength even at higher temperatures.

Recommended Uses

• Prototyping: Suitable for development and testing of new products and structural elements.
• Structural Components: Ideal for producing parts exposed to static pressure loads.
• Decorative and Aesthetic Parts: Thanks to its matte surface, it's suitable for producing decorative elements.

Printing Recommendations

Due to the carbon fibre content, it is recommended to use nozzles with a diameter larger than the standard 0.4 mm. Carbon fibres can cause wear to standard nozzles, therefore hardened steel or ruby nozzles are recommended for long-term use.

The Spectrum ReFill PET-G Carbon filament is an ideal choice for those seeking a material with excellent mechanical properties and aesthetic quality while maintaining an eco-friendly approach thanks to its spoolless design.
