About 3D Printing Nylon
3D printed nylon comes in many different forms, namely as a filament for FDM (fused deposition modeling) or as a powder for SLS (selective laser sintering) and MJF (HP Multi Jet Fusion) printing. 3D printing nylon creates parts with excellent properties but it’s important to understand that the type of 3D printing process will determine the final part capabilities. For example, FDM prints will have an anisotropic structure caused by the extruded layer lines. Even SLS-printed parts will have a level of anisotropy between layers. MJF parts tend to have isotropic properties, meaning the material will behave the same regardless of the direction of the load. However, with correct setups and part orientation, anisotropic effects can largely be negated and parts can benefit from the excellent properties of nylon.
Nylon is a high-performance engineering thermoplastic found in a wide range of industries. Its popular usage stems from its excellent abrasion resistance, high fatigue resistance, and high load-bearing capacity. Due to these properties, 3D printing in nylon is a great way to make lightweight industrial and medical implements that are just as capable as heavier metal ones.

FDM Nylon Materials
We offer two distinct Nylon variants through our Fused Deposition Modeling (FDM) process, enabling you to select the ideal balance of performance and stability for demanding applications.
- Stratasys Nylon 12 is suitable for large-scale parts demanding reliability and resilience. This high-grade formulation delivers exceptional dimensional stability, ensuring mechanical properties are retained over extended use. It is inherently resistant to shocks and fatigue, making it the perfect material for components that must endure repeated load/unload cycles and significant operational vibration.
- Nylon 6 CF is an excellent choice when your design requires maximum strength and stiffness with minimal weight. This composite utilizes carbon fiber chop reinforcement to create incredibly strong, stiff, and lightweight parts. This versatile material has been popularized by industry leaders, including Markforged Onyx, as well as other carbon-filled filaments from Bambu Lab, Polymaker, and others. It's highly suited for printing light-weight fixtures, clamps, and structural components that require superior performance and heat resistance.
Note that FDM materials are inherently anisotropic. This means the orientation of the deposited layers strongly influences the resulting mechanical properties. Our experts carefully consider the build orientation to optimize strength and performance, providing you with reliable, high-integrity components.

MJF Nylon Materials
Our Multi Jet Fusion (MJF) offering elevates Nylon's already excellent material properties, delivering production-ready parts with unmatched quality and consistency. MJF utilizes a unique fusing process that creates components with significantly greater isotropic properties and superior surface finish compared to FDM or FFF. Parts printed using MJF exhibit high detail and resolution, are inherently watertight, and are suitable for both rapid prototyping and end-use applications.
We offer multiple high-performance Nylon variants to meet your specific application needs:
- Nylon 12 is our "go-to" material for MJF, providing an excellent balance of mechanical strength, ductility, and chemical resistance. It is the ideal choice for general-purpose end-use parts, durable enclosures, and complex components.
- Nylon 11 is derived from renewable castor seeds, offering enhanced impact strength and ductility, making it more flexible and fracture-resistant. Use it for parts requiring higher flexibility, snap-fit features, and applications where fatigue resistance is critical.
- Nylon 12, Glass-filled (GF), is nylon 12 reinforced with glass beads. This variant provides significantly increased stiffness, rigidity, and dimensional stability. It is the best option for jigs, fixtures, and structural components that require higher temperature resistance and greater load-bearing capabilities.
- Nylon 12, White offers the same mechanical benefits as our standard Nylon 12, but with a bright white base, allowing for parts to be dyed a variety of vibrant colors. This material is well-suited for prosthetics, orthotics, and functional prototypes.
- Nylon 12, Smooth is a material specifically formulated to produce exceptionally smooth parts right off the machine. This material is a cost-effective choice for highly visible, end-use components. When paired with a vapor-smoothed finish, components are left with a finish rivaling that of injection-molded parts.
- Nylon 12, Multi-Color (CB) enables the production of full-spectrum color parts with functional engineering properties, perfect for architectural models and functional multi-color prototypes and assemblies complete with branding or photorealistic textures. Users who require a versatile and functional material but need to eliminate the time and cost associated with secondary painting or labeling will find great value in this option.

Cost-saving Design Tips
DFM: Each type of 3D printing technology requires special considerations during the design phase. For example, with FDM parts you should be mindful of support structures and consider the layer orientation that will generate maximum strength. SLS and MJF parts need drain holes to remove unused powder from internal cavities and should not have overly thick walls. Design-for-manufacturability (DFM) principles need to be applied from the start.
Choose the right plastic and process: Each of the above plastics and process combinations is better suited to certain applications. If the goal is to produce a temporary tooling jig, then Nylon 12 in FDM may be suitable. However, if a visual prototype is required, then SLS or MJF may better suit your needs. Use specialty or filled materials when the application demands it; otherwise, you may be paying more for characteristics you don't need.

Finishes
Xometry offers a wide range of surface finishes for nylon 3D prints, some of which are listed below. Visit our finishes page to learn about our other finishing options.
Standard: Available for all technologies and materials. Printing supports are removed from the part, but no additional work is done to the finish. Note that SLS and MJF parts have much better off-the-machine finishes than FDM and do not require the removal of support structures.
Color Dyeing: Parts are submerged in a dye solution that penetrates roughly ~0.010” into the surface, altering the surface’s color. Coloration may vary slightly from batch to batch. Available for SLS and MJF nylon parts.
Vapor Smoothing: Vapor smoothing creates a uniform, sealed surface with a semi-gloss appearance. It can be combined with our color dyeing option. Available for SLS and MJF nylon 12 parts.
Nickel plating: This surface treatment is not for cosmetic applications, as it creates a rough nickel finish. However, it adds additional durability, stiffness, and wear resistance. This finish is only available for SLS nylon parts.
