Nylon

Nylon in plain English

Nylon is what you pick when you’re done with “prototype plastics” and you need something that behaves like a serious engineering material. It’s valued for toughness, wear resistance, and fatigue performance — meaning it can survive repeated loading better than many rigid materials.

Nylon is not always the cheapest or fastest option, and it isn’t ideal for every geometry. But for the right part, it can be a big step up in real-world durability.

At a glance

When Nylon is the right choice

Choose Nylon when you need:

• a part that survives repeated stress (fatigue resistance)
• wear resistance (sliding contact, friction points)
• functional components that see real mechanical use
• a tougher feel than PLA/PETG for the same geometry

Examples:

• durable brackets and mounts under vibration
• bushings and wear pads (application-dependent)
• functional hinges and mechanical components
• workshop tooling where durability matters

If you’re building a part that must survive daily use and you can’t accept brittle failure, Nylon is often worth considering.

The key Nylon reality: moisture matters

Nylon naturally absorbs moisture from the air. That’s not a “problem” — it’s part of the material. But moisture affects printing quality and consistency, which is why handling and preparation matter.

For customers, you don’t need to worry about the details — just know that Nylon prints are treated as an engineering job where stability and preparation are part of doing it properly.

Design tips for Nylon parts

1) Avoid overly thin walls

Nylon is tough, but very thin walls can flex more than expected. If you need stiffness, consider:

• adding ribs
• increasing wall thickness slightly
• using a composite Nylon option (sourced on request) if stiffness is the main goal

2) Use fillets on stressed areas

Rounded corners reduce stress concentration and improve long-term durability.

3) Plan for movement and clearance

Nylon’s toughness makes it great for functional fits, but parts that mate with others still need practical clearance. If you have mating parts, share dimensions or send reference components.

4) Consider hardware and assembly

For fasteners, inserts, and durable interfaces, we can design for:

• heat-set inserts (where appropriate)
• captive nuts or mechanical clamping features

Nylon vs PETG vs composites

• PETG is the practical choice for many functional parts and is often faster and simpler.
• Nylon is the upgrade when you need fatigue and wear performance.
• Carbon-fibre composites are often used when maximum stiffness is the priority (with different trade-offs).

See:

• PETG
• Carbon‑fibre composites

What to tell us when quoting Nylon

Nylon choices are highly use-case driven. If you request Nylon, include:

• what loads the part sees (pulling, bending, vibration)
• whether it rubs or slides against other parts
• temperature exposure and environment
• whether stiffness or toughness is more important

FAQ

Is Nylon always better than PETG?

Not always. Nylon is excellent for certain functional jobs, but PETG can be a better value and more predictable for many parts. It depends on the use case.

Can Nylon be used outdoors?

It can, but the environment matters. If UV exposure is the main concern, ASA may be better for housings and brackets.

Is Nylon good for gears?

For some applications it can be, but gear performance depends on design, loads, lubrication, and mating material. Tell us the use case and we’ll advise.
