Filament ROSA3D PET-G CarbonLook 1.75 mm 1 kg spool

ROSA3D PET-G CarbonLook 1.75 mm filament on a 1 kg spool is formulated for FDM/FFF 3D printers requiring a balance of mechanical strength, dimensional stability, and an improved surface appearance. The PET-G base offers toughness and reduced brittleness compared with PLA, while the CarbonLook finish creates a textured, matte aesthetic resembling carbon-fiber without requiring a composite nozzle or special hardware. This filament is intended for users who need durable printed parts with a refined visual finish and consistent extrusion behavior.

Advantages

PET-G CarbonLook combines the chemical resistance and layer adhesion characteristics of PET-G with a textured visual effect that hides layer lines and delivers a professional-looking matte surface. The filament is available in 1.75 mm diameter on a 1 kg spool, providing compatibility with most consumer and prosumer FDM/FFF printers. Its formulation aims for reliable feeding, good inter-layer bonding, and lower odor during printing compared with some engineering plastics.

Suitable for

• Functional prototypes and mechanical parts that require impact resistance and dimensional stability
• Enclosures, fixtures, and jigs where a matte carbon-like appearance is desired
• Visual models and display pieces with improved surface texture
• Parts that need reliable extrusion and good layer adhesion for moderate stress applications

Key specifications

• Material: PET-G (polyethylene terephthalate glycol-modified)
• Appearance: CarbonLook textured matte finish
• Diameter: 1.75 mm
• Spool weight: 1 kg gross filament weight
• Compatibility: Standard FDM/FFF 3D printers with 1.75 mm filament path

How to use

Load the 1.75 mm PET-G CarbonLook filament into your FDM/FFF printer according to the printer manufacturer’s loading procedure. Recommended printing temperatures for PET-G typically range from 230–250 °C, but adjust within the printer’s capabilities to optimize extrusion and surface finish for the CarbonLook filament. Use a heated bed set between 70–90 °C to improve adhesion and reduce warping. Calibrate extrusion multiplier and retraction settings to minimize stringing while preserving the textured surface.

Usage recommendations

For best results, print with a moderate print speed and ensure good part cooling for overhangs. A hardened or wear-resistant nozzle is recommended when printing textured or slightly abrasive filaments to maintain dimensional accuracy over time. Store the spool in a dry environment or sealed container with desiccant to prevent moisture uptake, which can affect print quality.
