Filament Rosa3D PA12 + 15CF 1.75 mm 50 g — Black, carbon-fiber reinforced nylon

Rosa3D PA12 + 15CF is a carbon-fiber reinforced nylon filament in 1.75 mm diameter supplied on a 50 g spool in black. Formulated from PA12 matrix with 15% short carbon fiber content, the filament is intended for FDM/FFF 3D printers and provides improved stiffness, dimensional stability and wear resistance compared with unfilled PA12. The material balances the toughness and chemical resistance of nylon with increased rigidity from carbon fibers, making it suitable for functional prototypes and end-use components where reduced deformation and enhanced mechanical performance are required.

Advantages

The carbon-fiber reinforcement increases tensile stiffness and compressive strength while helping to control shrinkage and warping during printing. Compared with standard PA12, the composite shows better dimensional stability and surface rigidity, which supports tighter tolerances in printed parts. The filament's black color provides consistent aesthetic results for technical components, and its wear-resistant properties extend the service life of moving parts and interfaces.

Suitable for

• Functional prototypes that require higher stiffness and reduced deformation
• Mechanical parts such as brackets, housings and gears subjected to wear
• Fixtures, jigs and tooling where dimensional stability is important
• Small series production of durable components for testing and assembly

Key specifications

• Base polymer: PA12 (nylon)
• Filler: 15% short carbon fibers
• Diameter: 1.75 mm
• Spool weight: 50 g
• Color: Black
• Compatible technology: FDM / FFF 3D printing
• Properties: increased stiffness, improved dimensional stability, enhanced wear resistance

How to use

Print settings should be adjusted for a carbon-filled nylon filament: use a heated build plate and an enclosed or temperature-stable printing environment to reduce warping. Select a nozzle temperature and bed temperature appropriate for PA12-based materials and tune print speed and cooling to avoid delamination; consult your printer and hotend specifications for abrasive filaments since carbon fibers increase nozzle wear. Store the spool in a dry environment or sealed container with desiccant to prevent moisture uptake typical for nylon-based materials.

Usage recommendations

Use a hardened or wear-resistant nozzle to avoid accelerated abrasion, dry the filament before printing if necessary, and print with moderate layer heights and adequate part cooling control to optimize surface quality and dimensional accuracy.
