Spectrum PET-G Carbon Filament 1.75 mm 0.5kg / 1 kg

Improved hardness and stiffness

Spectrum PET-G Carbon is a modified PET-G filament blended with carbon fibers that contributes significantly higher stiffness, hardness, and tensile strength, while maintaining low shrinkage and excellent adhesion to build platforms typical of pure PET-G. The addition of 10% carbon fibers allows for matte surfaces on printed parts, significantly improving the aesthetic properties of the printed parts.

Tip: Due to the significant amount of ground carbon, we recommend using nozzles with diameters larger than the standard 0.4 mm. The presence of carbon fiber can also cause wear on brass nozzles, so we recommend using stainless steel nozzles for prolonged use of Spectrum PET-G Carbon.

Main features:

• improved hardness and stiffness compared to pure PET-G
• higher plasticizing temperature than pure PET-G
• improved abrasion resistance
• VICAT 80°C
• much higher compressive strength than pure PET-G
• good mechanical properties
• high aesthetic quality and matt surface
• no shrinkage after cooling

Applications:

• items that must be very rigid and hard while maintaining dimensional accuracy
• manufacturing of spacer components subjected to static compressive loads
• concept and demonstration prototyping of finished and semi-finished products designed
• ornamental parts (aesthetic properties)
• external structural components that highlight the product
• prototyping

Packaging

The filament is wound on a neat, transparent spool. Each spool contains information on the material type, diameter, and recommended printing temperature. The filament is vacuum-packed with a moisture absorber. The entire product is packaged in the original Spectrum Filaments film-lined packaging.

CHECK YOUR COIL : the most precise quality control system on the market

3D printer filament is produced using the free-flow extrusion method, which is one of the most challenging extrusion processing techniques due to the particularly high impact of process parameters on product size and material homogenization.

During production, every 1mm of Spectrum Filament is continuously measured on two axes with a precision of ±0.8µm, resulting in a high-quality final product. To demonstrate this, Spectrum Filaments is one of the few manufacturers in the world to offer the option of presenting online, individually for each spool produced:

• the course of the diameter along the entire length of the coil,
• average diameter,
• ovality,
• standard deviation.

Precise research ensures that Spectrum Filaments products meet the stringent market requirements.
