Spectrum 81346 Refill 3D filament, PET-G Carbon, 1.75mm, 1000g, Black

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     Filament Specifications:   - filament diameter: 1.75mm/2.85mm - extrusion temperature: 230-255°C - bed temperature: 60-80°C - print speed: 30-70mm/s
