ROSA3D PA 15CF black — Carbon-fiber reinforced PA filament for 3D printing, 1.75 mm

ROSA3D PA 15CF black is a carbon-fiber reinforced polyamide (PA) filament formulated for FDM/FFF 3D printing at 1.75 mm diameter. The addition of short carbon fibers increases stiffness, improves dimensional stability and enhances wear resistance compared to standard PA filaments. The matte black finish and reinforced mechanical properties make this filament suitable for functional prototypes, mechanical components and small-series parts that require improved rigidity and abrasion resistance. Use hardened or wear-resistant nozzles and appropriate temperature settings for polyamide materials to achieve consistent extrusion and layer adhesion.

Advantages

Carbon-fiber reinforcement raises tensile stiffness and reduces part deformation under load while retaining the chemical resistance and thermal characteristics of polyamide. The 1.75 mm diameter provides compatibility with most consumer and professional FDM printers. The material offers better dimensional stability and lower creep than unfilled PA, enabling printing of precise mechanical features and mating surfaces. The black coloration masks internal fiber structures and provides a uniform, technical appearance.

Suitable for

• Functional prototypes requiring higher stiffness and wear resistance
• Mechanical parts such as brackets, gears, bushings and housings
• Small-series production of durable components
• Applications where dimensional stability and low deformation are important

Key specifications

• Base material: polyamide (PA) reinforced with short carbon fibers
• Diameter: 1.75 mm
• Color: black (matte finish)
• Reinforcement: carbon fibers for increased stiffness and wear resistance
• Suitable printing technology: FDM/FFF
• Nozzle recommendation: hardened or wear-resistant nozzle
• Mechanical behavior: higher stiffness and improved dimensional stability vs. standard PA

How to use

Load the filament onto an FDM/FFF printer equipped with a hardened or wear-resistant nozzle to avoid abrasive wear from carbon fibers. Set extrusion temperatures according to polyamide processing guidelines, and adjust print speed and cooling to balance interlayer adhesion and surface finish. Use a heated build plate and, if available, an enclosed build chamber to reduce warping. Calibrate extrusion multiplier and retraction settings to accommodate the slightly abrasive and stiffer nature of the composite filament. Dry the filament before printing if ambient humidity is high to ensure optimal print quality.

Usage recommendations

For best results, print with hardened nozzle diameters of 0.4 mm or larger, maintain a stable build environment with a heated bed and moderate chamber temperature, and pre-dry filament at manufacturer-recommended conditions to minimize moisture-related defects. Avoid applications requiring high impact resistance or extreme flexibility; use this filament where stiffness and dimensional stability are priorities.
