What is Formlabs Nylon 12 White Powder?

Formlabs Nylon 12 White Powder is Formlabs' PA12 powder for Selective Laser Sintering on Fuse 1+ 30W — a white, dyeable PA12 powder for high-contrast prototypes, medical models, and customer-facing end-use parts. Formlabs Nylon 12 White Powder has a tensile strength of 47 MPa (6.82 ksi), stronger than 50% of polymer grades. Elongation at break is 8% and the elastic modulus is 1.95 GPa (0.283 Msi). Pick Formlabs in the Powder row when quoting PA12 and the part is printed from this powder.

Limitations

  • Higher moisture uptake — 1.4%, worse than 90% of polymer grades

Choosing Nylon 12 White Powder

White SLS PA12 for detailed, customer-facing parts that need a clean base colour or a controlled dyeing step.

Consider it for
High-contrast medical models and guides · Branded prototypes and low-volume housings · Fixtures where marks and surface damage should be easy to see
Tradeoffs
It is less ductile than Nylon 12 Tough, and Formlabs recommends nitrogen when colour consistency matters because printing in air can yellow reused powder. Published biocompatibility tests do not qualify a finished device.
Design and validation
Use the Fuse 1+ 30W process basis, preserve the published X/Y-versus-Z distinction for loaded features, and plan the required powder-aging and bed-temperature setup before production.
Finishing
White is the as-printed colour. Dyeing can add colour as a separate post-process, but the requested colour and application compatibility still need confirmation; blasting or tumbling can also change edge definition and surface texture.
Before choosing
Is a white or vividly dyed appearance more important than maximum ductility? Can the production workflow maintain the recommended nitrogen atmosphere?

How to interpret this data

The original formulation document keeps its manufacturer document ID even when the current live official PDF uses a different filename.

The TDS says properties may vary with part geometry, print orientation, and temperature.

The ASTM D570 water-absorption row does not state a 24-hour duration.

The TDS recommends inert atmospheric control for best results; current Formlabs guidance describes nitrogen as recommended rather than physically mandatory.

Formlabs Nylon 12 White Powder — frequently asked

What is Formlabs Nylon 12 White Powder used for?

White SLS PA12 for detailed, customer-facing parts that need a clean base colour or a controlled dyeing step. Consider it for high-contrast medical models and guides, branded prototypes and low-volume housings and fixtures where marks and surface damage should be easy to see. It is less ductile than Nylon 12 Tough, and Formlabs recommends nitrogen when colour consistency matters because printing in air can yellow reused powder. Published biocompatibility tests do not qualify a finished device.

What should I validate before using Formlabs Nylon 12 White Powder?

Use the Fuse 1+ 30W process basis, preserve the published X/Y-versus-Z distinction for loaded features, and plan the required powder-aging and bed-temperature setup before production. Is a white or vividly dyed appearance more important than maximum ductility? Can the production workflow maintain the recommended nitrogen atmosphere?

How can Formlabs Nylon 12 White Powder be finished?

White is the as-printed colour. Dyeing can add colour as a separate post-process, but the requested colour and application compatibility still need confirmation; blasting or tumbling can also change edge definition and surface texture.

How should I interpret the published values for Formlabs Nylon 12 White Powder?
