Filament ROSA3D PETG + CF 1.75 mm 1 kg — Black

ROSA3D PETG + CF 1.75 mm 1 kg — Black is a composite 3D printing filament that combines PETG thermoplastic with carbon fiber reinforcement. The material is supplied on a 1 kg spool in 1.75 mm diameter and is formulated to deliver increased stiffness, improved dimensional stability and better interlayer adhesion compared with standard PETG. This filament is intended for FDM/FFF printers that support abrasive or filled materials when using a suitable nozzle and printing setup.

Advantages

The carbon fiber reinforcement increases flexural rigidity and reduces part deformation while retaining many PETG properties such as chemical resistance and moderate heat tolerance. Layer adhesion and dimensional accuracy are improved, supporting stronger functional parts and prototypes. The filament’s black color provides a consistent matte-to-semi-matte surface finish suitable for visible functional components.

Suitable for

• Functional mechanical parts requiring higher stiffness
• Prototypes and structural components with improved dimensional stability
• End-use parts exposed to moderate temperatures and chemical environments
• Applications where a matte black, fiber-reinforced appearance is desirable

Key specifications

• Base polymer: PETG with carbon fiber reinforcement
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg
• Color: Black
• Material type: Composite, short carbon fiber-filled filament
• Compatibility: FDM/FFF 3D printers that can handle filled/abrasive filaments

How to use

Use this filament on FDM/FFF printers equipped to handle carbon fiber–filled materials. Install an abrasion-resistant nozzle (hardened steel, ruby or similar) to avoid accelerated wear. Recommended print temperatures and speeds depend on the specific printer and hotend; start with typical PETG settings and adjust: increase extrusion temperature and reduce printing speed if adhesion or flow issues occur. Ensure proper bed adhesion using a heated bed, suitable build surface or adhesive aid, and enable part cooling modestly depending on geometry. Dry the filament before use if it has been stored in humid conditions to avoid printing defects.

Usage recommendations

For best results, print with a hardened nozzle, keep retraction settings conservative to reduce clogs, and store the spool in a dry, sealed container with desiccant. Validate settings by printing a calibration part before producing critical functional components.
