Spectrum ReFill PET-G Carbon Black, 1.75 mm / 1000 g

ReFill PET-G Carbon from Spectrum is a spool-less filament wound on a cardboard core that is compatible with the reusable spools by Bambu Lab and the Spectrum spools* you can print yourself - no additional adapters are required. This environment-friendly option produces almost no waste and is available at an affordable price!

PET-G Carbon is a modified PET-G based filament that has been blended with 10% carbon fibre to significantly increase the rigidity, hardness and tensile strength of the material while maintaining low shrinkage and very good adhesion. The addition of carbon fibre lends an aesthetic, matte finish to the prints with no visible layer lines.

Note: Due to the high carbon fibre content, use nozzles with a diameter larger than the standard 0.4 mm when printing with PET-G Carbon. Furthermore, as the abrasiveness of carbon fibre can lead to increased wear on the nozzle, using a hardened stainless steel or ruby nozzle is recommended.

Properties of PET-G Carbon:

• 10% carbon fibre,
• Matte surface finish without visible layer lines,
• Improved hardness & rigidity,
• Improved abrasion resistance,
• Significantly increased pressure resistance,
• No shrinkage

►Suggested applications:

• Manufacture of hard and solid components (e.g. spacers),
• Manufacture of decorative items,
• Fabrication of external elements of a structure intended to emphasise the product design,
• Prototypes
