Formlabs Nylon 12 Tough Powder

Tough, Ductile SLS Powder for Functional Parts and Production

Formlabs Nylon 12 Tough Powder is a highly ductile SLS material developed for producing durable functional prototypes, end-use parts, and small-batch production components on the Fuse 1+ 30W.

Compared with standard Nylon 12 Powder, Nylon 12 Tough provides more than 50% greater elongation, helping parts withstand bending, impacts, and repeated mechanical loading without becoming brittle. The material also provides excellent dimensional accuracy across the build chamber and reduced warping, making it particularly well suited for long parts and components with challenging geometries.

One of its biggest advantages is its 20% refresh rate, allowing up to 80% of the powder in a build to be reused. This best-in-class refresh rate among Formlabs Nylon powders helps reduce material waste and lower the cost per part for prototyping and small-batch production.

Key Benefits

• High ductility: 25% elongation at break in the X/Y direction.

• Impact resistant: 60 J/m notched Izod impact strength.

• Reduced warping: Well suited for long parts and challenging geometries.

• Excellent dimensional accuracy: Maintains accurate parts across the build chamber.

• 20% refresh rate: Reuse up to 80% of powder per build.

• No support structures: SLS printing allows complex geometries without traditional support material.

• Functional performance: Suitable for durable prototypes and end-use components.

• Grey finish: Produces a consistent, professional-looking SLS surface.

Recommended Applications

Functional Prototypes
Create durable prototypes that can withstand handling, impacts, bending, and functional testing.

End-Use Parts
Produce low-volume production components and customized parts without the tooling investment associated with traditional manufacturing.

Snaps, Ratchets & Hinges
The material's high ductility makes it particularly useful for flexible mechanical features that need to withstand repeated movement.

Compliant Mechanisms
Produce mechanisms that rely on controlled deformation and flexibility.

Long Parts
Nylon 12 Tough is especially useful for elongated components that may be susceptible to warping. Formlabs reports reduced warping compared with standard Nylon 12 for long parts printed along the Z-axis.

Small-Batch Production
The combination of durable material properties and a low 20% refresh rate makes Nylon 12 Tough an economical option for producing functional parts in low to medium quantities.

Material Performance

Nylon 12 Tough Powder balances strength and stiffness with substantially higher ductility than standard Nylon 12. Its 25% X/Y elongation at break allows parts to flex and absorb impacts rather than failing prematurely.

Material properties are based on Formlabs' published data using aged powder and a temperature-tuned printer.

Powder Efficiency

20% Refresh Rate

Nylon 12 Tough Powder has a 20% recommended refresh rate, meaning up to 80% of the powder used in a build can be reused.

This is one of the material's biggest advantages for production environments. Lower powder consumption means less waste and a lower effective material cost per printed part.

Formlabs identifies Nylon 12 Tough as having the best-in-class refresh rate among its Nylon powders.

Printer Compatibility

Nylon 12 Tough Powder is specifically developed for the:

• Formlabs Fuse 1+ 30W

It is not compatible with the original Fuse 1. Formlabs' current powder compatibility information lists Nylon 12 Tough exclusively under Fuse 1+ 30W compatibility.

Printing Requirements

Nylon 12 Tough Powder requires additional preparation before its first production print.

Powder Aging

New Nylon 12 Tough Powder must undergo an initial powder aging process before the first print. This creates the recycled powder required for the material's recommended refresh-rate workflow.

Skipping the aging process can increase the risk of print failures and surface defects.

Bed Temperature Tuning

The Fuse 1+ 30W also requires bed temperature tuning before printing Nylon 12 Tough Powder. Formlabs recommends completing this tuning process on each printer that will use the material.

Printing Environment

Nylon 12 Tough Powder is designed to print in air on the Fuse 1+ 30W, with the recommended 20% refresh rate. Unlike certain Formlabs Nylon materials, nitrogen is not required for this material.

Post-Processing

SLS printing does not require traditional support structures, allowing complex geometries to be produced without generating support material.

After printing, parts are depowdered and cleaned using the Fuse Sift or compatible Fuse post-processing equipment. Nylon 12 Tough produces a relatively stiff powder cake, so depowdering may require somewhat more effort than standard Nylon 12.

Nylon 12 Tough vs. Standard Nylon 12

Nylon 12 Tough sacrifices some tensile strength and stiffness compared with standard Nylon 12 in exchange for substantially greater ductility and impact resistance.

Why Choose Nylon 12 Tough Powder?

Choose Formlabs Nylon 12 Tough Powder when your application requires durability, flexibility, and dimensional accuracy rather than maximum stiffness.

Its high ductility makes it especially useful for snaps, hinges, ratchets, compliant mechanisms, impact-resistant prototypes, and functional end-use components. Combined with its reduced warping and exceptionally low 20% refresh rate, Nylon 12 Tough is a strong choice for businesses looking to move from prototype quantities toward economical small-batch SLS production.
