Why Choose Nylon for 3D Printing?
Nylon is the workhorse material for functional 3D printed parts. As an engineering thermoplastic, it offers exceptional strength, durability, and flexibility — whether you need snap-fits, gears, brackets, or end-use production parts.
PrintVX uses calibrated industrial SLS systems for consistent mechanical properties batch after batch. Every part undergoes visual inspection before shipment.
Nylon Materials at PrintVX
PA12 (Nylon 12)
Most common SLS nylon. Excellent tensile strength, low moisture absorption, good chemical resistance. The preferred choice for most functional SLS parts.
PA11 (Nylon 11)
Bio-based from castor beans. Superior impact resistance and dimensional stability for demanding automotive and medical applications.
Glass-Filled PA12
Enhanced stiffness and heat resistance. Suitable for structural components requiring higher modulus than standard nylon.
Material Properties
| Property | PA12 | PA11 | Glass-Filled PA12 |
|---|---|---|---|
| Tensile Strength | 48 MPa | 45 MPa | 52 MPa |
| Impact Resistance | Good | Excellent | Good |
| Moisture Absorption | Very Low | Low | Low |
| Chemical Resistance | Excellent | Good | Excellent |
| Surface Finish | Fine matte | Fine matte | Slightly rough |
Key Advantages of SLS Nylon
- No supports needed — powder bed supports all geometries including overhangs, undercuts, and living hinges. Design freely without worrying about support removal marks.
- Isotropic properties — strength is consistent in all build directions, unlike FDM which has directional weakness between layers.
- Complex assemblies — snap-fits and living hinges printed as single pieces, eliminating assembly steps.
- No minimum order — order 1 piece or 10,000. Cost per part drops significantly at higher volumes due to shared powder bed setup costs.
- Fast turnaround — standard 3-5 business days. Express service available for urgent requirements.
Applications
Automotive & EV
Interior brackets, air vents, cable guides, and custom fixtures. Nylon heat resistance makes it suitable for under-hood environments and EV battery pack components.
Robotics & Automation
Gears, cable carriers, tool changers, and end-effectors. The combination of strength, flexibility, and low friction makes nylon ideal for moving components in robotic systems.
Medical Devices
Custom jigs, fixtures, and non-implant functional components. PA11 dimensional stability meets demanding medical requirements with full batch traceability.
Consumer Products
Wear-resistant cases, grips, and structural components for products ranging from sports equipment to industrial tools.
Design Guidelines
| Parameter | Minimum | Recommended |
|---|---|---|
| Wall Thickness | 0.8 mm | 1.5 – 3.0 mm |
| Minimum Feature | 0.3 mm | 0.8 mm+ |
| Clearance Between Parts | 0.3 mm | 0.5 mm+ |
| XY Accuracy | ±0.2 mm | ±0.3 mm |
Surface Finishing Options
- Bead blasting — uniform matte finish, removes loose powder, improves aesthetics
- Tumbling — smooths edges and achieves slightly polished surface
- Dyeing — black, grey, or custom colors for end-use parts
Frequently Asked Questions
What is the minimum order for nylon 3D printing?
No minimum order. We accept 1 piece orders. Pricing decreases as quantity increases due to shared powder bed setup costs.
Is SLS nylon food-safe?
Not certified as food-safe. The porous surface is unsuitable for direct food contact. Consult our team for food-grade alternatives.
How does SLS compare to injection molding?
SLS achieves 70-80% of injection molding tensile strength. For 1-1,000 pieces, SLS is often more cost-effective than investing in injection molding tooling which can cost $10,000-50,000+.
What file formats do you accept?
STL, STEP, IGES, and 3MF. STEP files are preferred for best quote accuracy.
