Carbon Fiber 3D Printing and Choose the Best Carbon Fiber Filaments

Carbon fiber 3D Printing can make robust parts with a detailed matte surface finish and discover the best carbon fiber filaments of 2023.

 

Carbon fiber 3D Printing is one of the most popular ways to make durable and tough parts with your desktop 3D printer. In this article, you can check out the best carbon fiber filaments with multiple material bases. Happy making!

Part 1. What is carbon fiber 3D Printing?

 

Before getting into the topic, let’s clarify what is carbon fiber 3D Printing exactly. Carbon fiber filaments are composite materials that infuse tiny carbon fiber to another polymer base materials, including nylon, PLA, PETG, ABS, etc. For example, if nylon materials that mix with tiny fibers, we call them carbon fiber nylon filaments. For consumer or desktop 3D printers, it is impossible to print straight carbon fiber because of the high melting point. While carbon fiber filaments contain short particles of fibers, which is only around 0.01mm in diameter. Carbon fiber filaments with the attributes of continuous fiber strands enhance material performance and mechanical properties, making it a feasible and suitable material to be printed by consumer 3D printers.

 

Besides, there are reasons that you might want to use carbon fiber filaments to create your 3D objects, let’s check it out.

Part 2. Why choose carbon fiber filaments?

 

By adding the tiny fibers, it can improve the quality of the base materials. Generally, carbon fiber filaments are stronger than standard materials such as PLA, PETG, and nylon, since carbon fiber is a remarkably strong material that brings higher stiffness and rigidity to the filaments. If your parts require light-weight design, carbon fiber filaments can achieve this instead of scarifying stiffness.

 

One of the biggest issues when printing thermal polymers is that the surface finish of the product might be granular. But carbon fiber filament wouldn’t let this happen. It can generate a flawless and high-quality matte surface finish. Besides, contraction is another common challenge during printing process as the melted material will be bonded with the previous-cooled layer of material together. The particles of carbon fiber filaments do not tend to contract, which ensures the dimensional stability and accuracy of your final parts.

 

If you are looking for durable and reliable materials to 3D print mechanical and assembly parts, carbon fiber filaments can be the alternatives and they won’t let you down.
