Sturdy Carbon Fiber Filament: Properties, How to Use, and Best Brands
In the debate of using PLA or ABS, the answer usually depends on the print being made. One of the most common considerations is the sturdiness of the final print. Although ABS prints are sturdier, they can also be quite brittle and don’t handle much stress before breaking. PLA, being more flexible, yields to stress and can absorb quite a bit before its breaking point. However, there is one material that reigns supreme in the contest of rigidity: carbon fiber filaments.
Understanding Carbon Fiber Filament
Carbon fiber filaments refer to a class of filaments made from various base materials infused with tiny carbon fibers. These fibers significantly enhance the durability of the printed product, increasing its stiffness and tensile strength. Carbon fibers are thin strands composed of carbon atoms bonded in a crystalline formation, providing an excellent strength-to-weight ratio.
Technical Features of Carbon Fiber Filaments
Here’s a comparison of the key technical features of carbon fiber filaments:
| Feature | Description |
|---|---|
| Strength-to-Weight Ratio | High, making it ideal for lightweight applications. |
| Durability | Excellent resistance to wear and tear, enhancing the lifespan of prints. |
| Heat Resistance | Can withstand high temperatures without deforming. |
| Dimensional Stability | Maintains shape and size during and after printing, reducing warping. |
| Abrasiveness | Can wear down standard brass nozzles; requires hardened steel nozzles. |
| Compatibility | Works with various base materials like PLA, ABS, PETG, and Nylon. |
Types of Carbon Fiber Filaments
Carbon fiber filaments come in various types, each with unique properties and applications. Here’s a comparison of the most common types:
| Type | Base Material | Carbon Fiber Content | Best Use Cases |
|---|---|---|---|
| PLA Carbon Fiber | PLA | 30% | General 3D printing, prototypes |
| ABS Carbon Fiber | ABS | 20% | Functional parts, automotive components |
| PETG Carbon Fiber | PETG | 20% | High-temperature applications |
| Nylon Carbon Fiber | Nylon | 30% | Strong, flexible parts |
| Polycarbonate Carbon Fiber | PC | 20% | High-impact applications |
Benefits of Using Carbon Fiber Filament
The main strengths of carbon fiber lie in its excellent strength-to-volume ratio and very high strength-to-weight ratio. This gives excellent rigidity and durability to materials while being much lighter compared to traditional durable materials such as wood, steel, or aluminum. It also exhibits very good resistance against corrosion and chemical degradation.
Working with Carbon Fiber Filament
When working with carbon fiber filaments, it’s essential to adjust your printer settings based on the base material. For instance, if you are printing with carbon-fiber infused ABS, you can use the optimal settings for ABS.
Nozzle Considerations:
Due to the hardness of carbon fibers, standard brass nozzles can wear down quickly. It is recommended to use hardened steel nozzles to maintain print quality.
Temperature Settings:
You may need to set your printing temperature 20 to 40 °C higher than usual to prevent clogging at the extruder due to cooling down of the filament.
Retraction Settings:
Disabling retractions can help avoid clogging issues, as the carbon fibers do not melt with the base plastic material.
Applications of Carbon Fiber Filament
Carbon fiber filaments are widely used in various industries, including aerospace, automotive, and sporting goods. They are ideal for applications where weight is a critical consideration, such as in wing spars, automotive wheels, and bicycle frames.
Best Brands of Carbon Fiber Filament
Several brands offer high-quality carbon fiber filaments. Here are some of the most popular options:
– ColorFabb XT-CF20: A PETG-based filament infused with 20% carbon fiber, known for its strength and dimensional accuracy.
