What is Formlabs Nylon 12 GF Powder?
Formlabs Nylon 12 GF Powder is Formlabs' PA12 (GF-filled) powder for Selective Laser Sintering on Fuse 1+ 30W, Fuse 1 — a glass-filled PA12 powder for rigid, dimensionally stable parts under sustained loading and elevated temperatures. Formlabs Nylon 12 GF Powder has a tensile strength of 38 MPa (5.51 ksi), weaker than 56% of polymer grades. Elongation at break is 4% and the elastic modulus is 2.8 GPa (0.406 Msi). Pick Formlabs in the Powder row when quoting PA12 and the part is printed from this powder.
Limitations
- Limited ductility — 4%, worse than 78% of polymer grades

Choosing Nylon 12 GF Powder
Glass-filled Formlabs PA12 for stiff, dimensionally stable SLS parts exposed to sustained loads or elevated temperature.
- Consider it for
- Rigid manufacturing fixtures and tooling · Thermally stressed housings · Low-strain structural components
- Tradeoffs
- Glass filling raises stiffness and heat resistance while leaving little elongation for snaps or notch-sensitive features. The reinforcement is dispersed glass filler, not continuous fibre.
- Design and validation
- Use generous radii and avoid thin compliant tabs. Validate the loaded orientation and long-term creep case, and keep the choice within the published Fuse 1 or Fuse 1+ 30W workflow.
- Finishing
- Gray is the as-printed colour. Dye or coating availability can differ from unfilled PA12, so confirm the exact colour and adhesion route on a representative coupon.
- Before choosing
- Will stiffness, creep resistance or heat exposure govern the design? Would unfilled PA12 or Nylon 12 Tough better tolerate impact or repeated flexing?

How to interpret this data
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 solvent section says printed and post-cured but defines no SLS post-cure. This wording does not establish an SLS post-cure requirement.
The document names sustained loading as an application but publishes no creep curve or long-duration load value.
Formlabs Nylon 12 GF Powder — frequently asked
What is Formlabs Nylon 12 GF Powder used for?
Glass-filled Formlabs PA12 for stiff, dimensionally stable SLS parts exposed to sustained loads or elevated temperature. Consider it for rigid manufacturing fixtures and tooling, thermally stressed housings and low-strain structural components. Glass filling raises stiffness and heat resistance while leaving little elongation for snaps or notch-sensitive features. The reinforcement is dispersed glass filler, not continuous fibre.
What should I validate before using Formlabs Nylon 12 GF Powder?
Use generous radii and avoid thin compliant tabs. Validate the loaded orientation and long-term creep case, and keep the choice within the published Fuse 1 or Fuse 1+ 30W workflow. Will stiffness, creep resistance or heat exposure govern the design? Would unfilled PA12 or Nylon 12 Tough better tolerate impact or repeated flexing?
How can Formlabs Nylon 12 GF Powder be finished?
Gray is the as-printed colour. Dye or coating availability can differ from unfilled PA12, so confirm the exact colour and adhesion route on a representative coupon.
How should I interpret the published values for Formlabs Nylon 12 GF Powder?
Fuse 1; specimens conditioned at 23 °C and 50% relative humidity for 7 days before testing. Elongation is reported separately for X/Y (4%) and Z (3%). The other table values do not state an orientation. Read each value with the stated method, specimen preparation and conditioning.
