Material overview
PA12 (nylon 12) is the workhorse SLS powder. Laser-sintered fully without supports, it produces tough, near-isotropic parts with a uniform matte finish, good chemical resistance and biocompatible / skin-contact grades. It is the default choice for functional prototypes, enclosures, ducting, jigs and small-batch end-use parts — and takes dyeing, vapor smoothing and painting cleanly.
Highlights
- No supports — complex geometry & internal channels
- Near-isotropic strength (XY & Z)
- Biocompatible skin-contact grades
- Finish: dye · vapor-smooth · paint
