3D Filament Flashforge 1.75 mm 500 g Carbon Fiber (FG171-CABK)

Flashforge 3D Filament 1.75 mm 500 g Carbon Fiber is a composite filament formulated to provide higher stiffness and improved dimensional stability compared with standard thermoplastic filaments. Offered on a 500 g spool in 1.75 mm diameter, this carbon fiber blend is intended for users who need stronger, lightweight printed parts while maintaining good surface quality. The filament is compatible with printers that support composite materials and requires appropriate extrusion hardware and tuned print settings.

Advantages

This carbon fiber filament increases part rigidity and reduces warping and shrinkage relative to ordinary filaments. It allows the production of functional prototypes and end-use components with improved mechanical performance and a matte textured finish. The material typically prints with good layer adhesion and dimensional repeatability when used with a hardened nozzle and adjusted print parameters.

Suitable for

• Functional prototypes and mechanical test parts
• Lightweight structural components and housings
• Jigs, fixtures and tooling aids
• Models requiring improved stiffness and thermal stability

Key specifications

• Filament diameter: 1.75 mm
• Spool weight: 500 g
• Material type: carbon fiber reinforced thermoplastic blend
• Finish: matte, slightly textured surface
• Compatibility: suitable for FDM/FFF printers capable of handling composite filaments

How to use

Load the filament into a printer equipped with a hardened or wear-resistant nozzle to avoid abrasion from carbon fibers. Set print temperature and bed temperature according to the base polymer used in the composite, and adjust retraction, print speed and layer height to balance surface quality and strength. Calibrate extrusion multiplier and first-layer settings to ensure consistent flow and good adhesion to the build surface.

Usage recommendations

Use a hardened steel or ruby-tipped nozzle, maintain a dry storage condition to prevent moisture uptake, and test a small sample part when first integrating the filament into a workflow. Monitor printer hardware for increased wear when printing composite materials and adjust slicer settings for best mechanical results.
