EOS PA 3200 GF
PA12, glass-filledPowderSLSEOS
Quick answer
EOS PA 3200 GF is a glass-bead-filled PA12 SLS powder (40 wt% glass beads per EOS). Filling raises tensile modulus to 3200 MPa — roughly double unfilled PA 2200 — with 51 MPa tensile strength and 9% elongation at break, for stiff housings and wear-resistant machine components.
PA 3200 GF is EOS's stiff SLS nylon. The base polymer is PA12, filled with 40 wt% glass beads — beads, not fibres, per the EOS data sheet. Spherical bead filler raises stiffness and dimensional stability in all directions more evenly than fibre filling would.
The trade is ductility: elongation falls to 9% in-plane (5.5% in Z) from PA 2200's 18%. This is a material for parts that must not flex — housings under load, fixtures, forming tools — not for clips or hinges.

Processing notes
- SLS powder for EOS polymer systems.
- EOS does not publish a melting temperature for this grade (the field is blank in the current data sheet), so none is listed here.
- Density is 1.22 g/cm³ (EOS method), reflecting the glass content; parts are noticeably heavier than unfilled PA12.
Typical applications
- Machine components needing enhanced stiffness under load, e.g. housings
- Heavily used parts needing wear and abrasion resistance
- Forming tools
Frequently asked questions
Is PA 3200 GF filled with glass fibre or glass beads?
Glass beads. EOS specifies a white PA12 powder filled with 40 wt% glass beads. Bead filling stiffens more isotropically than short-fibre filling.
How much stiffer is PA 3200 GF than PA 2200?
Tensile modulus is 3200 MPa vs 1650 MPa in the XY plane — close to double. Elongation at break halves in exchange (9% vs 18%).
When should I avoid PA 3200 GF?
For parts that must flex, snap or absorb impact: its 9% elongation and bead-filled structure make it comparatively brittle. Unfilled PA12 or PA11 serve those applications better.
