PA12-GB
Glass-bead Nylon 12
Stiff parts · Dimensional stability
PA12 with glass beads — stiffer and more dimensionally stable, same MJF process. The trade is toughness: it gives up tensile strength and flex to get there.

SECTION · 01
Strengths
& uses
For parts that need more stiffness or warp resistance than standard PA12.
Strengths
- Tensile modulus 2800–2900 MPa — over 60 % stiffer than PA12
- Heat deflection 121 °C at 1.82 MPa — well above PA12's 95–106
- Less warp — holds dimension across large, flat geometry
- Weaker and more brittle than PA12 — stiff, not strong, by design
Common applications
- Housings that must not warp
- Tooling and fixtures
- Precision jigs and gauges
- Dimensionally critical parts
