What is Nylon12 CF (Carbon Filled)?
PA12 CF15 is a composite material consisting of polyamide 12 (Nylon 12) reinforced with 15% carbon fiber. Nylon is naturally strong and flexible, but the addition of carbon fiber makes the material stiffer and stronger, without making it too heavy. Carbon fiber gives the filament extra strength and makes it particularly suitable for technical and industrial applications where high mechanical requirements are imposed.
Features of PA12 CF15:
- Excellent strength and stiffness: PA12 CF15 offers a significant improvement in strength and stiffness over standard Nylon, thanks to the carbon fiber reinforcement.
- Lightweight: The carbon fiber makes PA12 CF15 lighter than standard Nylon, which is important for applications where light weight is essential.
- Dimensional stability: PA12 CF15 has low shrinkage and minimal distortion during printing, ensuring highly accurate and stable prints.
- High heat and chemical resistance: The material retains its mechanical properties at higher temperatures and is resistant to various chemicals and oils.
Applications of Nylon12 CF (Carbon Filled)
PA12 CF15 is often used in applications where both strength and light weight are essential. Here are some of the most common uses of PA12 CF15:

3. Mechanical Fixings and Tools
PA12 CF15 is perfect for making mechanical fasteners, clamps and industrial tools that need to be wear-resistant and durable. The combination of stiffness and lightness makes it ideal for these applications.
4. Functional Prototypes and Final Products
For functional prototypes that require extensive mechanical testing, PA12 CF15 is an excellent choice. The material provides strength, stiffness and durability, making it suitable for harsh environments.
5. Sports equipment
Due to the combination of lightweight and high strength, PA12 CF15 is often used in sports equipment such as bicycle parts, protection and other performance materials that must withstand mechanical stress, but at the same time be light and comfortable.
Advantages of Nylon12 CF (Carbon filled)
PA12 CF15 offers numerous advantages that make it a powerful and versatile material for demanding applications. Here are the main benefits:
- High strength and stiffness: Due to the carbon fiber reinforcement, PA12 CF15 is significantly stronger and stiffer than standard PA12, making it ideal for structural applications.
- Lightweight: The addition of carbon fiber makes the material lighter, which is important for automotive and aerospace applications where weight is a critical factor.
- Dimensional stability: PA12 CF15 has minimal shrinkage and distortion during printing, making it possible to produce highly accurate and stable parts.
- High heat and chemical resistance: The material retains its mechanical properties at higher temperatures and is resistant to various chemicals, such as oils and fuels.
- Wear resistant: PA12 CF15 has good wear resistance, making it suitable for parts that are used for long periods of time and intensively.
Disadvantages of Nylon12 CF (Carbon filled)
Despite the advantages, there are some disadvantages and challenges when printing with PA12 CF15 that you should consider:
- Higher cost: PA12 CF15 is more expensive than standard filaments due to the addition of carbon fiber, making it less suitable for simple or cost-sensitive projects.
- Abrasive for nozzles: The presence of carbon fiber makes PA12 CF15 very abrasive, meaning you need a hardened steel nozzle to prevent wear.
- Higher printing temperatures required: PA12 CF15 requires higher printing temperatures (typically between 260°C and 300°C), meaning not all 3D printers can handle this material.
- More difficult to print: Due to the stiffer nature of the material and higher printing temperatures, PA12 CF15 can be more difficult to print, making it less accessible to beginners.
- Low flexibility: Although PA12 CF15 is very strong and stiff, it offers less flexibility than other materials such as standard Nylon or TPU.
3D printing with Nylon12 CF (Carbon filled)
Printing with PA12 CF15 requires precise settings and suitable equipment to achieve the best results. Here are some tips for successful printing with PA12 CF15:
1. Use a hardened nozzle
PA12 CF15 is very abrasive due to the addition of carbon fiber. Therefore, use a hardened steel nozzle or other wear-resistant nozzle to prevent the nozzle from wearing out quickly. Brass nozzles can quickly become damaged due to the abrasive nature of the filament.
2. Higher printing temperatures
Printing with PA12 CF15 requires higher printing temperatures, usually between 260°C and 300°C. Make sure your 3D printer is suitable for these temperatures. A heated print bed is also important and should be set between 80°C and 110°C to ensure good adhesion and minimal warpage.
3. Heated print chamber recommended
A heated print chamber can help reduce shrinkage and distortion, especially on larger prints. Keeping the ambient temperature stable ensures that the print cools evenly, leading to more accurate and durable parts.
4. Use a suitable printing surface
PA12 CF15 adheres best to printing surfaces such as PEI or polypropylene tape, and adhesives such as glue stick can also assist with adhesion. This prevents warping and ensures that the part remains properly on the print bed during printing.
5. Slower print speeds for better precision
Because PA12 CF15 is stiffer than many other filaments, it is advisable to work at lower print speeds, around 30-50 mm/s. This ensures better layer adhesion and increases the precision and quality of the printed parts.
Frequently asked questions about Nylon12 CF (Carbon filled)
1. What is the difference between PA12 CF15 and PA12 GF15?
PA12 CF15 is reinforced with carbon fiber, while PA12 GF15 is reinforced with fiberglass. Carbon fiber makes the material lighter and stiffer, while fiberglass provides greater strength and impact resistance, but is slightly heavier than carbon fiber.
2. Is PA12 CF15 more difficult to print than standard filaments?
Yes, PA12 CF15 requires higher printing temperatures and a hardened nozzle due to the abrasive nature of the filament. It can also be more prone to warping, which requires extra attention during printing.
3. Do I need a heated print bed for PA12 CF15?
Yes, a heated print bed is essential for printing with PA12 CF15. A temperature of 80°C to 110°C helps improve adhesion and reduce warping during the printing process.
4. Can I use PA12 CF15 for outdoor applications?
Yes, PA12 CF15 has good resistance to UV radiation, moisture and chemicals, making it suitable for outdoor applications and use in aggressive environments.
5. Is PA12 CF15 recyclable?
Yes, PA12 CF15 is recyclable, but it may depend on local recycling programs. Check the guidelines for recycling engineering plastics in your region.
6. How can I prevent wear on my nozzle when printing with PA12 CF15?
Always use a hardened steel nozzle or other wear-resistant nozzle, as PA12 CF15 is very abrasive due to the carbon fiber. Avoid using standard brass nozzles as they will wear out quickly.
