It’s important to understand the limits and complexities of 3D printing carbon fiber. While 3D printing carbon fiber is possible, it’s not generally recommended for automotive use. In this blog post, we’ll explore the limits of 3D printed carbon fiber, why it’s not generally recommended for automotive use, and why it’s often better to buy a part made using traditional carbon manufacturing methods.
What are the limits of 3D printed carbon fiber?
3D printed carbon fiber is made by combining short carbon fibers with a thermoplastic base material. While 3D printed carbon fiber composites have exceptional strength and stiffness, they have some limitations. The fibers can cause nozzle blockages in the 3D printer, which can compromise the surface finish of the 3D printed object. Additionally, the length of the chopped carbon fiber must be far less than the diameter of the extrusion nozzle, typically 0.4mm wide. If the segments were longer than that, they’d quickly clog the nozzle. This limits the length of the carbon fiber segments that can be used in 3D printing.
Why is 3D printed carbon fiber not generally recommended for automotive use?
Automotive parts require high strength and durability to withstand the stresses of driving. While 3D printed carbon fiber composites are strong, they are not as strong as parts made using traditional carbon manufacturing methods. Additionally, 3D printed carbon fiber composites are more prone to delamination, which can cause the part to fail. For these reasons, 3D printed carbon fiber is not generally recommended for automotive use.
Why is it often better to buy a part made using traditional carbon manufacturing methods?
Parts made using traditional carbon manufacturing methods are designed to fit perfectly and are made to the same specifications as the original part. This ensures that the replacement part will perform as well as the original part. Additionally, parts made using traditional carbon manufacturing methods are stronger and more durable than 3D printed carbon fiber composites. This is because traditional carbon manufacturing methods use continuous carbon fibers, which are stronger than the short carbon fibers used in 3D printed carbon fiber composites. While parts made using traditional carbon manufacturing methods are more expensive than 3D printed carbon fiber composites, they are worth the investment in the long run.
In conclusion, while 3D printed carbon fiber composites have exceptional strength and stiffness, they have some limitations. Due to these limitations, 3D printed carbon fiber is not generally recommended for automotive use. It’s often better to buy a part made using traditional carbon manufacturing methods, which are stronger and more durable than 3D printed carbon fiber composites. By following these guidelines, you can ensure that your carbon fiber parts are safe and reliable.
