FDM nylon (polyamide) is a popular material in 3D printing, especially for applications that require high resilience, temperature resistance and wear resistance. But not all nylon is the same - different types have different properties that are suitable for specific areas of application. Here is an overview of which nylon material is the best choice and when.
PA6-GF: Glass fiber-reinforced nylon for stability and rigidity
PA6-GF contains glass fibers that increase the stiffness and dimensional stability of the material. This material is ideal for applications where mechanical loads occur and deformation must be minimized.
- Area of application: machine components, housings, tools.
- Advantages:
- Outstanding rigidity.
- More cost-effective compared to carbon fiber reinforced nylon.
- Special features: Can be somewhat more brittle due to the glass fibers.
PA6-CF: Carbon fiber-reinforced nylon for maximum performance
PA6-CF is reinforced with 20% carbon fibers, which results in an exceptionally high tensile strength. It also offers ESD safety (electrostatic discharge capability), which makes it particularly popular in the electronics industry.
- Area of application: Functional prototypes, lightweight components, electronic housings.
- Advantages:
- Very high tensile strength.
- Lighter than glass fiber reinforced nylon.
- Suitable for demanding industrial applications.
- Special features: High wear resistance and good temperature resistance.
PA12-CF: Carbon fiber-reinforced nylon for moisture resistance
PA12-CF is characterized by its low sensitivity to moisture. It retains its mechanical properties even in damp environments and offers excellent surface quality.
- Area of application: Components that are exposed to moisture or changing environmental conditions, such as automotive components or outdoor applications.
- Advantages:
- Stable mechanical properties in damp conditions.
- Superior surface quality.
- Special features: Minimal tendency to warp, even with large components.
Summary of materials and applications
| Material | Main advantage | Suitable for |
|---|---|---|
| PA6-GF | Stiffness, dimensional stability | Machine components, tools |
| PA6-CF | Highest tensile strength, ESD protection | Functional prototypes, electronic housings |
| PA12-CF | Moisture resistance | Outdoor applications, automotive components |
Further considerations when choosing materials
- Temperature resistance: PA6-CF is particularly suitable for applications with high temperatures.
- Lightweight construction: If weight plays a role, carbon fiber-reinforced nylon (PA6-CF or PA12-CF) is advantageous.
- Moisture sensitivity: PA12-CF is the best choice for applications in humid environments or with fluctuating conditions.
With the right choice of FDM nylon material, specific requirements can be optimally fulfilled.
