Description
Improved hardness and stiffness
Spectrum PET-G Carbon is a modified filament based on PET-G mixed with carbon fibers, which contributes to significantly higher stiffness, hardness, and tensile strength while maintaining low shrinkage and very good adhesion to build platforms typical for pure PET-G. A 10% addition of carbon fibers allows for obtaining matte surfaces of printed materials, which significantly enhances the aesthetic properties of the prints.
Tip: Given the substantial content of chopped carbon fire, it is recommended to use nozzles with a diameter exceeding the standard value of 0.4 mm. The presence of carbon fibers can also cause wear on standard nozzles; therefore, for long-term application of Spectrum Carbon PET-G, it is recommended to use hardened steel or ruby nozzles.
Key Features:
- improved hardness and stiffness compared to pure PET-G
- higher plasticization temperature compared to pure PET-G
- improved abrasion resistance
- much higher compression resistance compared to pure PET-G
- good mechanical properties
- high aesthetic quality, matte finish
- no shrinkage after cooling
Applications:
- objects that need to be very rigid and hard while maintaining dimensional accuracy
- production of spacer components exposed to static pressure load
- concept and demo prototyping of designed finished and semi-finished products
- decorative parts (aesthetic properties)
- external structural elements that emphasize the product
- prototyping
