FDM – ASA+CF (Carbon Fiber)

ASA+CF is a high-performance carbon fiber reinforced ASA [acrylonitrile styrene acrylate] filament ideal for anyone that desires a structural component with high modulus, excellent surface quality, dimensional stability, and light weight. Made using 15% High-Modulus Carbon Fiber (not carbon powder or milled carbon fiber).

Key Material Facts:

• High UV and Weather Resistance: ASA is known for its excellent resistance to UV light and harsh environmental conditions, making ASA+CF a great choice for outdoor applications.
• Increased Strength and Stiffness: The addition of carbon fiber significantly improves tensile strength and rigidity compared to standard ASA. This makes it suitable for structural components that need to withstand mechanical loads.
• Good Heat Resistance: ASA already has a high glass transition temperature (~100°C), and with carbon fiber reinforcement, ASA+CF can handle higher temperatures without warping.
• Dimensional Stability & Reduced Warping: Carbon fiber reduces the material’s tendency to warp, improving dimensional accuracy and reducing the need for a heated chamber.
• Matte Surface Finish: Carbon fibers provide a smooth, matte finish, which enhances aesthetics and minimizes the visibility of layer lines.
• Chemical Resistance: ASA itself is resistant to many chemicals, including oils, greases, and certain solvents, making ASA+CF suitable for industrial applications.

Common Applications:

• Outdoor parts (drones, automotive components, enclosures)
• Functional prototypes requiring strength and UV resistance
• Mechanical and industrial parts with high stiffness requirements
