VoxTech3D PA-12 is a production-grade SLS nylon 12 powder that delivers the balance the material is famous for: 48 MPa tensile strength with 30% elongation at break, high impact toughness (20 kJ/m² Charpy), and good corrosion and chemical resistance. Sintered parts are rated for long-term service, making PA-12 the workhorse choice for functional prototypes, end-use components, housings, brackets, ducting, and living hinges.
Because SLS builds in a self-supporting powder bed, PA-12 parts need no support structures — complex geometries, interior channels, and consolidated assemblies print as designed, and nested builds keep unit costs low at quantity. The powder is compatible with both fiber-laser and CO₂-laser sintering platforms, with a 120°C heat deflection temperature giving finished parts real thermal headroom in service.
The black grade produces a uniform, deep-black part straight out of the build — no dyeing step — with a finish that hides handling marks and reads as a molded production component.
VoxTech3D PA-12 Black is the production SLS workhorse: tough, chemical-resistant nylon 12 parts in a uniform black finish, straight off the build.
